Hi! I'm using postfix 2.5 and configured LDAP as lookup table for my virtual map like this:
ldapvirtualfoobar_server_host = ldap://myserver:389 ldapvirtualfoobar_search_base = dc=my,dc=ldap,dc=base ldapvirtualfoobar_query_filter = (&(objectClass=someClass)(someAttribute=%s)) ldapvirtualfoobar_result_attribute = mail ldapvirtualfoobar_result_filter = %s The main problem is that "mail" is a multivalue attribute and nearly all of the found LDAP objects contain multiple values for "mail". In this case the incoming mail gets duplicated. "size_limit=1" does only limit the number of found LDAP objects per LDAP query (which is always 1 in my case). "expansion_limit=1" causes a temporary error if more than one mail address is returned during lookup. Is there any way to return only one address by LDAP query if result_attribute is a multivalue attribute? It doesn't matter which one of the values is returned. The more I read the docs I get the feeling that it's currently not possible but maybe you know a less-known/undocumented trick.
