You can configure a SAN Volume Controller cluster to use remote authentication.
A remote user is authenticated on a remote service usually provided by a SAN management application, such as IBM® Tivoli® Storage Productivity Center. Remote users require no local credentials to access the SAN Volume Controller Console. Remote users have their groups defined by the remote authentication service. If a remote user needs to use the command-line interface, both a password and SSH key are required. If the remote authentication service fails, then remote users cannot access the SAN Volume Controller Console or the command-line interface. In this situation, a local user with the Security Administrator role must change remote users to local users by adding them to the appropriate user group. After logging in to a SAN Volume Controller application, a remote user is granted access to the SAN Volume Controller CLI and Console by default.
