To allow access to the Vibe site through NetIQ Access Manager, you need to make configuration changes in NetIQ Access Manager to configure a protected resource for a Vibe server as described in Configuring a Protected Resource for a Vibe Server.
IMPORTANT:When NetIQ Access Manager (or another single sign-on tool) is used in conjunction with your Vibe system, external users and the Guest user cannot access your Vibe site.
For more information about external users in Vibe, see Understanding External Users.
