= 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.=

With VTLUUG uses [[Infrastructure:Chimera|chimera]] as it's FreeIPA server, and all VTLUUG hosts except [[Infrastructure:Joey|joey]], the current deployment acidburn should be acceptable through normal password authentication over ssh. There is no need to configure tickets or anything else Kerberos relatedrouter, are in its domain.

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 (razorlog into [https://chimera.vtluug.org) using ldapmodify and .ldif files Chimera's FreeIPA web GUI] to change attributes as well.
