LDAP Syntax in LDAP Filter

[yvangodard]

The LDAP filter seems to be a little bit freakish.
For example this filter doesn't work :
groupfilter = (&(objectClass=posixGroup)(cn=staff)(cn=workgroup))
but this one works fine :
groupfilter = (&(objectClass=posixGroup)(!(cn=staff))(!(cn=mtoocadmin))(!(cn=mtoml_))(!(cn=corepsconnect))(!(cn=itmonitoring))(!(cn=ml-icc_)))

It's a generic LDAP filters for python-ldap library, and for LDAP implementation(C) itself. Nothing to do here.
