mailing lists in LDAP

[David Wright <ichbin@shadlen.org>]

I am having trouble managing mailing lists in LDAP. I want each mailing 
list to be a single object in the LDAP database. I have been trying to 
use groupOfNames for the purpose.

I am using Postfix, where I can specify a query filter and result 
attribute. Postfix wants the result attribute to be an email address. 
But the member attribute of gruopOfNames is required to be a DN, not an 
arbitrary string.

So, can someone suggest...

1) how to construct a filter which will follow the DN references of the 
member attributes and get their mail attributes, or

2) a different group objectClass that will allow arbitrary strings for 
members.

Just running slapd with schemacheck off is not an option. :-)
