Hi listers,

I have ~40 departments in several ou's and I need an ACL to allow access for one user to all but one OU.

I do not want to forbid that ou in question and thus implicitly allowing all the others. I want to formulate this explicitly, so I can directly see what is allowed.

Moreover the names of the ou's are very similar to each other, something like: ou=aaaa,dc=... ou=abaa,dc=... ou=bbaa,dc=... ou=bbbb,dc=...

and suppose I want to disallow access to the ou=abaa.

I ended up with two ACLs: the first one to forbid ou=abaa:

access to dn.sub=ou=abaa,dc=.... \ attrs=entry by dn=uid=foo,dc=.... none by * break

and then allowing access to all ou's with

access to dn.regex=ou=[^,]+,dc=... \ attrs=.... by dn=uid=foo,dc=... by * break

Is it possible to formulate this with just one ACL ? I tried something like "ou=!abaa" with just the second ACL but failed.

Then I tried ou=[^a][^b][^a][^a] but this matches also the ou=bbbb to wich the uid=foo should have access.

Let me answer this question by myself for completeness:

use a filter is the answer: filter=(!(ou:dn:=abaa)) in my example above does the trick.
