I have mentioned that we may need slapo-memberof.

&gt;<i> - we use slapo-dynlist ( same page )
</I>&gt;<i> 
</I>&gt;<i> slapo-memberof seems to be what we want, but this doesn't seems dynamic

</I>
No real issue ...

&gt;<i> slapo-dynlist seems overkill.
</I>&gt;<i> 
</I>&gt;<i> Any LDAP guru to give insight ?
</I>
slapo-dynlist has some issues when used to provide features like slapo-
memberof. Specifically, you can't filter on the dyanmic values, so e.g. search 
for &quot;(&amp;(objectClass=posixAccount)(memberof=cn=mageia-xxx,ou=Group....)
(uid=foo))&quot; is not feasible to try and determine authorization in a single 
search.

So, I think we have only two options, and using slapo-memberof may be the best 
(as it solves the problem for other clients). There are some caveats, but in 
our deployment they should not matter.

Buchan
