In setups with big databases and sldap size limits, creating a users fails:

udm users/user create ...
LDAP Error: Administrative limit exceeded


 uldap.search filter=(objectClass=*) base=cn=Domain Users,cn=groups,o=in8,o=orange scope=sub attr=['gidNumber'] unique=0 required=0 timeout=-1 sizelimit=0

The problem is this:

 self.lo.search(base=self['primaryGroup'], attr=['sambaSID'])

This search uses the ldap filter filter=(objectClass=*). Seems that slapd applies the filter and than checks the limits (before filtering the search base).

The search works with a proper scope "scope=base" but we may better use uldap.get or uldap.getAttr instead.

Attached a patch that fixes this problem for "udm users/user create" (with scope=base). But there are much more of those searches in our udm handlers.
