When you modify a password, the new password expires automatically; it is valid only once (unless you specify /NOPWDEXPIRED). On login, users are forced to change their passwords (unless you specify /FLAGS=DISFORCE_PWD_CHANGE).

Note that the /GENERATE_PASSWORD and /PASSWORD qualifiers are mutually exclusive.

/INTERACTIVE[ =(range[,...])]

/NOINTERACTIVE

/JTQUOTA=value

/LGICMD=filespec

/LOCAL[=(range[,...])]

/MAXACCTJOBS=value

/MAXDETACH=value

/MAXJOBS=value

/NETWORK[=(range[,...])]

/OWNER=owner-name

/PASSWORD=(password1[,password2])

/NOPASSWORD

Uppercase and lowercase characters are equivalent. All lowercase characters are converted to uppercase before the password is encrypted. Avoid using the word password as the actual password.

Use the /PASSWORD qualifier as follows:

• To set only the first password and clear the second, specify /PASSWORD=password.
• To set both the first and second password, specify /PASSWORD=(password1, password2).
• To change the first password without affecting the second, specify /PASSWORD=(password, "").
• To change the second password without affecting the first, specify /PASSWORD=("", password).
• To set both passwords to null, specify /NOPASSWORD.

When you modify a password, the new password expires automatically; it is valid only once (unless you specify /NOPWDEXPIRED). On login, the user is forced to change the password (unless you specify /FLAGS=DISFORCE_PWD_CHANGE).

Note that the /GENERATE_PASSWORD and /PASSWORD qualifiers are mutually exclusive.

By default, the ADD command assigns the password USER. When you create a new UAF record with the COPY or RENAME command, you must specify a password. Avoid using the word password as the actual password.

/PBYTLM

/PGFLQUOTA=value

If decompressing libraries, make sure to set PGFLQUOTA to twice the size of the library.

/PRCLM=value

/PRIMEDAYS=([NO]day[,...])

By default, primary days are Monday through Friday and secondary days are Saturday and Sunday. If you omit a day from the list, AUTHORIZE uses the default value. (For example, if you omit Monday from the list, AUTHORIZE defines Monday as a primary day.)

Use the primary and secondary day definitions in conjunction with such qualifiers as /ACCESS, /INTERACTIVE, and /BATCH.

/PRIORITY=value

/PRIVILEGES=([NO]privname[,...])

/PWDEXPIRED (default)

/NOPWDEXPIRED

/PWDLIFETIME=time (default)

/NOPWDLIFETIME

To prevent a password from expiring, specify the time as NONE. By default, a password expires in 90 days.

/PWDMINIMUM=value

/QUEPRIO=value

/REMOTE[=(range[,...])]

/SHRFILLM=value

/TQELM

/UIC=value

Each user must have a unique UIC. By default, the UIC value is [200,200].

/WSDEFAULT=value

The value cannot be greater than WSMAX. This quota value replaces smaller values of PQL_MWSDEFAULT.

/WSEXTENT=value

The value is an integer equal to or greater than WSQUOTA. By default, the value is 1024 pages on VAX systems and 16384 pagelets on Alpha and I64 systems. The value cannot be greater than WSMAX. This quota value replaces smaller values of PQL_MWSEXTENT.

/WSQUOTA=value

The value cannot be greater than the value of WSMAX and cannot exceed 8,192 pagelets on Alpha and I64 systems. This quota value replaces smaller values of PQL_MWSQUOTA.

Description

When you do not specify a value for a field, AUTHORIZE uses values from the DEFAULT record (excluding the default password, which is always USER). The DEFAULT account serves as a template for creating user records in the system user authorization file.

On Alpha and I64 systems, the DEFAULT account is as follows:

Username: DEFAULT Owner: Account: UIC: [200,200] ([DEFAULT]) CLI: DCL Tables: DCLTABLES Default: [USER] LGICMD: Flags: DisUser Primary days: Mon Tue Wed Thu Fri Secondary days: Sat Sun No access restrictions Expiration: (none) Pwdminimum: 6 Login Fails: 0 Pwdlifetime: 90 00:00 Pwdchange: (pre-expired) Last Login: (none) (interactive), (none) (non-interactive) Maxjobs: 0 Fillm: 128 Bytlm: 128000 Maxacctjobs: 0 Shrfillm: 0 Pbytlm: 0 Maxdetach: 0 BIOlm: 150 JTquota: 4096 Prclm: 8 DIOlm: 150 WSdef: 4096 Prio: 4 ASTlm: 300 WSquo: 8192 Queprio: 4 TQElm: 100 WSextent: 16384 CPU: (none) Enqlm: 4000 Pgflquo: 256000 Authorized Privileges: NETMBX TMPMBX Default Privileges: NETMBX TMPMBX

On VAX systems, the DEFAULT account is as follows:

Username: DEFAULT Owner: Account: UIC: [200,200] ([DEFAULT]) CLI: DCL Tables: DCLTABLES Default: SYS$SYSDEVICE:[USER] LGICMD: LOGIN Flags: DisUser Primary days: Mon Tue Wed Thu Fri Secondary days: Sat Sun No access restrictions Expiration: (none) Pwdminimum: 6 Login Fails: 0 Pwdlifetime: 90 00:00 Pwdchange: (pre-expired) Last Login: (none) (interactive) (none) (non-interactive) Maxjobs: 0 Fillm: 300 Bytlm: 32768 Maxacctjobs: 0 Shrfillm: 0 Pbytlm: 0 Maxdetach: 0 BIOlm: 40 JTquota: 4096 Prclm: 2 DIOlm: 40 WSdef: 256 Prio: 4 ASTlm: 40 WSquo: 512 Queprio: 0 TQElm: 10 WSextent: 1024 CPU: (none) Enqlm: 200 Pgflquo: 32768 Authorized Privileges: TMPMBX NETMBX Default Privileges: TMPMBX NETMBX

When you add a new account, specify values for fields that you want to be different. Typically, changing the default values for limits priority, privileges, or the command interpreter is not necessary. As a result, you enter only the password, UIC, directory, owner, account, and device.

Note Limits are also set by system parameters. To be effective, the limits you set through AUTHORIZE must be within the minimum limits determined by the corresponding system parameters (particularly those beginning with the PQL prefix).

When you add a record to the UAF, create a directory for the new user. Specify the device name, directory name, and UIC in the UAF record. The following DCL command creates a directory for user ROBIN:

$ CREATE/DIRECTORY SYS$USER:[ROBIN] /OWNER_UIC=[ROBIN]

Note When you add a new record to the UAF and a rights database exists, an identifier with the user name is added to the rights database automatically (unless you specify the /NOADD_IDENTIFIER qualifier). Similarly, when you specify an account name (other than the user name) that does not yet have an identifier, AUTHORIZE creates a group identifier in the rights database.

Examples

UAF> ADD ROBIN /PASSWORD=SP0152/UIC=[014,006] -
_/DEVICE=SYS$USER/DIRECTORY=[ROBIN]/OWNER="JOSEPH ROBIN" /ACCOUNT=INV
%UAF-I-ADDMSG, user record successfully added
%UAF-I-RDBADDMSGU, identifier ROBIN value: [000014,000006] added to
  RIGHTSLIST.DAT
%UAF-I-RDBADDMSGU, identifier INV value: [000014,177777] added to
  RIGHTSLIST.DAT
      

This example illustrates the typical ADD command and qualifiers. The resulting record from this command appears in the description of the SHOW command.

UAF> ADD WELCH /PASSWORD=SP0158/UIC=[014,051] -
_/DEVICE=SYS$USER/DIRECTORY=[WELCH]/OWNER="ROB WELCH"/FLAGS=DISUSER -
_/ACCOUNT=INV/LGICMD=SECUREIN
%UAF-I-ADDMSG, user record successfully added
%UAF-I-RDBADDMSGU, identifier WELCH value: [000014,000051] added to
      RIGHTSLIST.DAT
UAF> MODIFY WELCH/FLAGS=(RESTRICTED,DISNEWMAIL,DISWELCOME, -
_NODISUSER,EXTAUTH)/NODIALUP=SECONDARY/NONETWORK=PRIMARY -
/CLITABLES=DCLTABLES/NOACCESS=(PRIMARY, 9-16, SECONDARY, 18-8)
%UAF-I-MDFYMSG, user records updated
      

The commands in this example add a record for a restricted account. Because of the number of qualifiers required, a MODIFY command is used in conjunction with the ADD command. This helps to minimize the possibility of typing errors.

In the ADD command line, setting the DISUSER flag prevents the user from logging in until all the account parameters are set up. In the MODIFY command line, the DISUSER flag is disabled (by specifying NODISUSER) to allow access to the account. The EXTAUTH flag causes the system to consider the user as authenticated by an external user name and password, not by the SYSUAF user name and password.

The record that results from these commands and an explanation of the restrictions the record imposes appear in the description of the SHOW command.

ADD/IDENTIFIER

Adds only an identifier to the rights database. It does not add a user account.

Format

ADD/IDENTIFIER [id-name]

Parameter

id-name

Specifies the name of the identifier to be added to the rights database. If you omit the name, you must specify the /USER qualifier. The identifier name is a string of 1 to 31 alphanumeric characters. The name can contain underscores and dollar signs. It must contain at least one nonnumeric character.

Qualifiers

/ATTRIBUTES=(keyword[,...])

Specifies attributes to be associated with the new identifier. The following keywords are valid:

DYNAMIC	Allows unprivileged holders of the identifier to remove and to restore the identifier from the process rights list by using the DCL command SET RIGHTS_LIST.
HOLDER_HIDDEN	Prevents people from getting a list of users who hold an identifier, unless they own the identifier themselves.
NAME_HIDDEN	Allows holders of an identifier to have it translated, either from binary to ASCII or from ASCII to binary, but prevents unauthorized users from translating the identifier.
NOACCESS	Makes any access rights of the identifier null and void. If a user is granted an identifier with the No Access attribute, that identifier has no effect on the user's access rights to objects. This attribute is a modifier for an identifier with the Resource or Subsystem attribute.
RESOURCE	Allows holders of an identifier to charge disk space to the identifier. Used only for file objects.
SUBSYSTEM	Allows holders of the identifier to create and maintain protected subsystems by assigning the Subsystem ACE to the application images in the subsystem. Used only for file objects.

By default, none of these attributes is associated with the new identifier.

/USER=user-spec

Scans the UAF record for the specified user and creates the corresponding identifier. Specify user-spec by user name or UIC. You can use the asterisk wildcard to specify multiple user names or UICs. Full use of the asterisk and percent wildcards is permitted for user names; UICs must be in the form [*,*], [n,*], [*,n], or [n,n]. A wildcard user name specification (*) creates identifiers alphabetically by user name; a wildcard UIC specification ([*,*]) creates them in numerical order by UIC.

/VALUE=value-specifier

Specifies the value to be attached to the identifier. The following formats are valid for the value-specifier:

IDENTIFIER:n	An integer value in the range of 65,536 to 268,435,455. You can also specify the value in hexadecimal (precede the value with %X) or octal (precede the value with %O). The system displays this type of identifier in hexadecimal. To differentiate general identifiers from UIC identifiers, the system adds %X80000000 to the value you specify.
GID:n	GID is the POSIX group identifier. It is an integer value in the range 0 to 16,777,215 (%XFFFFFF). The system will add %XA400.0000 to the value you specify and then enter this new value into the system RIGHTSLIST as an identifier.
UIC:uic	A UIC value in standard UIC format consists of a member name and, optionally, a group name enclosed in brackets. For example, [360,031]. In numeric UICs, the group number is an octal number in the range of 1 to 37776; the member number is an octal number in the range of 0 to 177776. You can omit leading zeros when you are specifying group and member numbers. Regardless of the UIC format you use, the system translates a UIC to a 32-bit numeric value. Alphanumeric UICs are not allowed.

Typically, system managers add identifiers as UIC values to represent system users; the system applies identifiers in integer format to system resources.

Examples

UAF> ADD/IDENTIFIER/VALUE=UIC:[300,011] INVENTORY
%UAF-I-RDBADDMSGU, identifier INVENTORY value: [000300,000011]
added to RIGHTSLIST.DAT
      

The command in this example adds an identifier named INVENTORY to the rights database. By default, the identifier is not marked as a resource.

UAF> ADD/IDENTIFIER/ATTRIBUTES=(RESOURCE) -
_/VALUE=IDENTIFIER:%X80011 PAYROLL
%UAF-I-RDBADDMSGU, identifier PAYROLL value: %X80080011 added to
RIGHTSLIST.DAT
      

This command adds the identifier PAYROLL and marks it as a resource. To differentiate identifiers with integer values from identifiers with UIC values, %X80000000 is added to the specified code.

ADD/PROXY

Adds an entry to the network proxy authorization files, NETPROXY.DAT and NET$PROXY.DAT, and signals DECnet to update its volatile database. Proxy additions take effect immediately on all nodes in a cluster that share the proxy database.

Format

ADD/PROXY node::remote-user local-user[,...]

Parameters

node

Specifies a DECnet node name. If you provide a wildcard character (*), the specified remote user on all nodes is served by the account defined as local-user.

remote-user

Specifies the user name of a user at a remote node. If you specify an asterisk, all users at the specified node are served by the local user.

For systems that are not OpenVMS and that implement DECnet, specifies the UIC of a user at a remote node. You can specify a wildcard character (*) in the group and member fields of the UIC.

local-user

Specifies the user names of 1 to 16 users on the local node. If you specify an asterisk, a local-user name equal to remote-user name will be used.

Positional Qualifier

/DEFAULT

Establishes the specified user name as the default proxy account. The remote user can request proxy access to an authorized account other than the default proxy account by specifying the name of the proxy account in the access control string of the network operation.

Description

The ADD/PROXY command adds an entry to the network proxy authorization files, NETPROXY.DAT and NET$PROXY.DAT, and signals DECnet to update its volatile database. Proxy additions take effect immediately on all nodes in a cluster that share the proxy database.

You can grant a remote user access to one default proxy account and up to 15 other local accounts. To access proxy accounts other than the default proxy account, remote users specify the requested account name in an access control string. To change the default proxy account, use the AUTHORIZE command MODIFY/PROXY.

Proxy login is an effective way to avoid specifying (and, possibly, revealing) passwords in command lines. However, you must use caution in granting access to remote users. While logged in to the local system, remote users can apply the full DCL command set (with the exception of SET HOST). A remote user receives the default privileges of the local user and, therefore, becomes the owner of the local user's files when executing any DCL commands.

To avoid potential security compromises, HP recommends that you create proxy accounts on the local node that are less privileged than a user's normal account on the remote node. By adding an extension such as _N, you can identify the account as belonging to a remote user, while distinguishing it from a native account with the same name on the local node. For example, the following command creates a JONES_N proxy account on the local node that allows the user JONES to access the account from the remote node SAMPLE:

UAF> ADD/PROXY SAMPLE::JONES JONES_N/DEFAULT %UAF-I-NAFADDMSG, record successfully added to NETPROXY.DAT

For more information about creating proxy accounts, refer to the HP OpenVMS Guide to System Security.

Examples

UAF> ADD/PROXY  SAMPLE::WALTER   ROBIN/DEFAULT
%UAF-I-NAFADDMSG, record successfully added to NETPROXY.DAT
      

Specifies that user WALTER on remote node SAMPLE has proxy access to user ROBIN's account on local node AXEL. Through proxy login, WALTER receives the default privileges of user ROBIN when he accesses node AXEL remotely.

UAF> ADD/PROXY MISHA::* MARCO/DEFAULT, OSCAR
%UAF-I-NAFADDMSG, record successfully added to NETPROXY.DAT
      

Specifies that any user on the remote node MISHA can, by default, use the MARCO account on the local node for DECnet tasks such as remote file access. Remote users can also access the OSCAR proxy account by specifying the user name OSCAR in the access control string.

UAF> ADD/PROXY MISHA::MARCO */DEFAULT
%UAF-I-NAFADDMSG, record successfully added to NETPROXY.DAT
      

Specifies that user MARCO on the remote node MISHA can use only the MARCO account on the local node for remote file access.

UAF> ADD/PROXY TAO::MARTIN  MARTIN/D,SALES_READER
%UAF-I-NAFADDMSG, proxy from TAO:.TWA.RAN::MARTIN to MARTIN added
%UAF-I-NAFADDMSG, proxy from TAO:.TWA.RAN::MARTIN to SALES_READER
added
      

Adds a proxy from TAO::MARTIN to the local accounts MARTIN (the default) and SALES_READER on a system running DECnet-Plus.
