VTLUUG has been was Kerberos and LDAP for authentication until the [[CVL eviction]]. We have now migrated to an LDAP only domain due to a lack of IPv6 on behind router.ece.vt.edu. The old Kerberos server was configured to work on IPv6 only therefore we were required to migrate away from its use for authentication.

All users will be able to use standard shell commands (such as chsh) to change attributes of their own account. Additionally they can make direct requests to the LDAP server (razor.vtluug.org) using ldapmodify and .ldif files to change attributes as well. Explaining .ldif files and ldapmodify is beyond the scope of this article.
