i went back to one of my old system to try and get you an answer.
We purchased the LDAP module, but were never really ready to pull the trigger.
1) One annoying thing is that we were going to use Automatic login - since all users would already be logged in to the domain/network.
But this has to be done only using IE, and they were not going to force everyone to do that.
2) But, when using the automatic login (directlogin.aw i think) then it just took them in and they don't have to preface their id - but you probably know that.
3) So, you also have to have a non-direct login page where you manually enter LoginName. when I went back to this system, it brought up the "saved" values in the LoginName field and it had BOTH "Jaymer" and "XXUSA\Jaymer" - so I can't tell. I tried to alter the Login Options to go back to using LDAP but then I couldn't login at all and spent 15 mins trying to get in - the system wouldn't generate the "m_LDAPSETTINGS" file so I couldn't get anywhere. Had to revert to non-LDAP logins. Been over a year.
wish I could help.
jaymer...
