To use LDAP to authenticate users on Windows PCs, you can use the pGina dynamically linked library. pGina is available from http://pgina.org
Setup instructions by ITS DLUS (Distributed Learning and User Services) are available in the document, Configuring pGina for LDAP Authentication For Windows XP.
In the section, Configure pGina, you can leave the Admin User and Admin Pass values blank if you don't need to authenticate UH students. This is because students are not publicly visible in LDAP and can't be found unless a special DN and password is used to connect to the directory server. Faculty and staff are publicly visible in LDAP so no Admin User and Pass are needed.
If you want to authenticate UH students, you will need to request a special DN.
Windows 7 users may need to add the IP address and hostname for the UH LDAP server, ldap1.its.hawaii.edu, to the Windows hosts file.
Campuses may want to limit PC usage to students, faculty, and staff at that campus. To do this, go to the pGina configuration screen and change the Filter from (uid=%s) to something like (&(uid=%s)(uhOrgAffiliation=eduPersonOrgDn=kcc,eduPersonAffiliation=*)) . In this example, the eduPersonOrgDn value is kcc for Kapiolani Community College.
Values for eduPersonOrgDn are:
