make 'ldap trust ids' the default?

[Andrew Bartlett]

I've just committed a patch that adds a new 'ldap trust ids' smb.conf
option.

Currently defaulting to off, this option allows pdb_ldap to use the ldap
server directly to determine if a user 'exists' in unix.

This gives us a performance boost, particularly on enumerations: 
(Removes the extra lookup per record).  

The logic is such that if there are no posixAccount attributes for a
user, we try getpwnam(), it's just that we look in LDAP first.

As such, do people think we should have this by default?  

This was a fix to solve some particular problems that metze had, and
I'll see if I can get some feedback on exactly how much this helps.
