Re: Global ACLs - Impacts access control and SLAPI (ITS#3100)

I don't think it is broke, but intended behavior:

If their are global acls, they apply to all databases
after any db acls.  If the db has no acls, global acls
are used.

If the target is not within any database, acls of
first database (then global acls) apply.

It's been this way for many years (long before SLAPI).
