= 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.=
==Account maintenance instructions==''Main article: [[VTLUUG:LDAP Info]]''
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. Explaining edit their account.ldif files and ldapmodify is beyond the scope of this articleYes, it does have a self signed cert.Get over it /s
For management of the entire domain , officers who know the LDAP root users credentials will be are able to log add, remove, or modify users in to the LDAP Administrator web application running on razor.vtluug.org. Information on this is really only shared on a need to know basis between officers, and the content is not entirely appropriate for a public wikiany way.
== History == VTLUUG has been was Kerberos and LDAP for authentication until the [[CVL eviction]]. We then 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 the old deployment, [[Infrastructure:Acidburn|acidburn]] should be acceptable through normal password authentication over ssh. There is no need to configure tickets or anything else Kerberos related. = CAS = The '''Virginia Tech Central Authentication System''' or '''CAS''' is the Virginia Tech deployment of the [[Free software|open source]] [[w:Shibboleth (Internet2)|Shibboleth]] authentication system. Shibboleth can be thought of as an identity provider similar to [[w:OpenID|OpenID]], but more centralized, and thus well-liked by institutions such as universities. == Scripted Login ==The following is a work in progress.
