Hi,

The attached patch allow the autogroup overlay to handle correctly the attr part
of the URL ldap://dc=example,dc=com?attr?sub?(filter). Before this patch, the
attr part was simply ignored. Now the group entry is populated by the values of
the attribute attr in the resulting entries.

Implementation details:
Some cases (modify, delete) are harder to handle when you store values instead
of dn. In this cases the overlay try to detect if groups have been modified and
then simply refresh them. This can cause performance hits if the search
specified by the URL deals with an important number of entries.
