Authenticating users by group using LDAP?

[benton]

Hello, all.

I need to secure some resources that are external to Zimbra through Zimbra's LDAP interface. Authenticating individual users is no problem, but the only way I can see to aggregate users in Zimbra (Distribution Lists, right?) does net seem to appear as a groupOfUniqueNames in Zimbra's OpenLDAP database (or as any other object, for that matter).

I really do not want to have to maintain lists of external individual users for every external resource. Ideally, each Distribution List would be either stored or mirrored as a groupOfUniqueNames, which is the standard way for storing group info in LDAP.

Surely others have this need as well... is it possible? What solutions have others come up with?

Thanks in advance,
