Ask the Wizard Questions

Order of security checks with ACLs

The Question is:

Is it possible to for VMS to get "confused" if I have an ACL defined along with UIC protections? I have looked into the manual and I conclude "no"- but I think I should ask the experts. The reason I ask is that my sys admin. suggested that, somehow, the VMS is getting confused because both are defined.

The Answer is:

No - the documentation is very clear on the order in which security checks are made. The ACL is scanned first - if there are no matches in the ACL, then the traditional protection mask is looked at. For more information, refer to the OpenVMS Guide to System Security.
