Indiana University uses both Microsoft Active Directory Services and MIT Kerberos for authentication. The University uses a custom password changing tool passphrase.iu.edu to keep these systems synchronized. Drupal supports both types of authentication through modules. The two modules used were LDAP Integration Module and Webserver_Auth module. The first attempt was to use LDAP Integration; however, after following all of the recommendations on setup a TLS error could not be overcome. The web server already supports MIT Kerberos authentication using directives added to a “.htaccess” file, so the Webserver_Auth module allows use of MIT Kerberos which works very well.
