saslauthd,ldap,virtual_domains

[Kervin L. Pierre]

Is there are way to dynamically modify ldap_search_base attribute of 
saslauthd so that it searches are particular DIT of the LDAP server?

eg. a way to split the realm ( %r ) macro, then building a search base 
off that. ie.

ldap_search_base: ou=people,%d

Where %d explodes to "dc=domain,dc=tld", derived from the realm, %r.

I say this because I think it's a fairly common setup to have domains as...
ou=people,dc=domain1,dc=tld
ou=people,dc=domain2,dc=tld
...
Or maybe I'm just weird :)

Has this been done?  Is it somehow necessary?

Thanks,
