function ldap_sso_user_login in LDAP Single Sign On 6

A proxy function for the actual authentication routine. This is in place so various implementations of grabbing NTLM credentials can be used and selected from an administration page. This is the real gatekeeper since this assumes that any NTLM authentication from the underlying web server is good enough, and only checks that there are values in place for the user name, and anything else that is set for a particular implementation. In the case that there is no credentials set by the underlying web server, the user is redirected to the normal user login form.

Return value
