apache2 mod_auth_ldap with multiple ldap servers not working...

Failing to get it working under 1.3.x I figure it's time to finally
move to apache2.

Well, I can't get mod_auth_ldap to support multiple ldap servers.

Our basedn includes spaces, ie "o=My Organization, c=US", so I already
had problems with just using one server until I figured out I had to
put the whole string in quotes. We also use a non standard port.

The following string (one server) works fine:

AuthLDAPURL "ldap://my.server.net:12345/o=My Organization,
c=US?uid?sub?"

But then adding a second server it won't work at all, specially that
you have to quote everything under one set of quotes, or else the
module complains that it only accepts one argument.

Also, it's not clear if you need to specify the base for each server
(but it doesn't make a difference).

Basically, the same problem I had with Dave's auth_ldap for 1.3...

AuthLDAPURL "ldap://my2.server.net:12345 ldap://my.sever.net:12345/o=My
Organization, c=US?uid?sub?"

The above hits the first server (my2.server.net) but the server being
down, it fails to roll over to the next one.

Any one gotten this to work under similar conditions (ie spaces in the
base and/or nonstandard ports) ? Currently the module is compiled
using Openldap libraries - haven't tried with iPlanet's yet, though for
auth_ldap under 1.3 I had and didn't work either...

TIA...
