[Samba] multiple ldap servers

[Nathan Ehresman]

Hello,

I was looking at the ldap authentication code (in 2.2.5) and it looks 
like there is no support for having multiple ldap servers for 
authentication (ie, if one is not responding, try from a backup).  Does 
anyone have a patch to add this functionality?  If not, I'll go ahead 
and do it but I wanted to check to see if it has already been done first.

Thanks,

Nathan Ehresman
