When I run the AdminUI and I try to login, the AdminUI fails to establish trusted connection with Policy Server and it reports the below error:
ERROR [Bootstrap] Failed to establish trust with the Policy Server, use 'XPSExplorer' on the Policy Server to clean up CA.SM::TrustedHost and CA.SM::Admin objects
Adminui installation should be independent of the Policy Server, and so it should not be running with the same user as the Policy Server if you have both Policy Server and the AdminUi installed and running on the same machine.
There should also be only 1 AdminUI instance running on a given machine.
Siteminder version: 12.5.0 Build 732
Running the AdminUI with a different user and having a single AdminUI instance on the machine resolved the issue.
