The LDAP support won't affect this directly.

With LDAP support, the information that would otherwise appear in 
/etc/passwd now is stored in LDAP, and that isn't just your password, 
but your username, the gecos field, your uid and gid, etc.

The tricky bit may be the bit that stops password logins being possible, 
because the simple way of doing it - removing the password - also 
removes your ability to use the password against other LDAP services, 
like svn.

I would imagine there is a way to configure PAM to say "if user is 
member of group | not member of group | has this attribute | whatever 
don't permit a login with a password", but that will have to be 
experimented with.

Regards,
Graham
