= 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 (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.
For management of the entire domain, officers are able to add, remove, or modify users in any 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.
