Setting up AD (Active Directory) for TLS to allow for Password changing.

Description:

Active Directory will not allow passwords to be updated unless the LDAP communication is encrypted.

The standard method of encrypted LDAP communication is TLS/SSL. To make the AD TLS/SSL capable a certificate must be generated. If you have a CA the the following needs to be done:

1. Got to Start->Programs->Administrative Tools->Domain Security Policy.
2. Go to Security Settings->Public Key Policies->Automatic Certificate Request Settings , right click and select New Automatic Certificate Request.
3. Select Domain Controller from the window, then select your CA.

If you do not have a CA the following article might be useful: http://support.microsoft.com/kb/321051
