I've discovered a problem with the way AIX uses auditclasses to determine which system calls are audited. If a user is defined in LDAP, their auditclasses attribute is blank. I found an APAR which states, prior to AIX 5.3, the default user stanza in /etc/security/audit/config was applied to users without an auditclasses attribute. However, this no longer seems to be the case in AIX 5.3 or higher.
I know there's a RFC2307AIX schema, which defines this LDAP attribute. However, I'd like to set a local default auditclasses and not have to convince the Active Directory admins to apply a schema extension. Besides, I cannot find a schema extension for eDirectory, which is also used.
Has anyone else seen this problem?
