[RCD] Is it possible to use a separate filter for searching members of LDAP contact group?

Dear developers,

Is it possible to use a separate filter for searching members of LDAP contact group in Roundcube-0.6-beta? I'm not so clear how to achieve this after reading comment in main.inc.php.dist.

Currently, my LDAP structure looks like below:

• All groups are placed under ou=Groups,dc=xxx. e.g. mail=group01@domain.ltd

,ou=Groups,dc=xxx.

• Group members are placed under ou=Users,dc=xxx, e.g.

mail=user01@domain.ltd,ou=Users,dc=xxx, with attribute 'memberOfGroup=group01@domain.ltd' to identify group membership.

How can i list members of contact group in Roundcube Address Book? Maybe add 'filter_members' in "groups => array();" like below:

'groups' => array( 'filter_members' => '(memberOfGroup=%u)', ... ),

Thanks for your great work, and looking forward to your reply.
