ldap_bind returns error 49 Invalid credentials

[dbair]

I am able to connect to my AD server successfully.  This server serves multiple domains.

Example is user1@dom1.dom.net is able to successfully bind.

    user2@dom2.com is not able to bind but gets error 49: invalid credentials.

 

Using windows ldp.exe, I can connect successfully, then select bind from the connection menu, enter the username (user2), the account password, and the Domain (dom2.com) and the result indicated is successful.

 

Using php I attempt to bind using:

$adBind = ldap_bind($ad, $adUname, $ldappass);

Where $ad = successful connection resource, $adUname = user1@dom1.dom.com OR user2@dom2.com, $ldappass is the account password.

As user1 it is successful, with user2 it is unable to bind with error 49.

Any suggestions or help is greatly appreciated.

 

Thanks in advance!
