[SmAuthServer.cpp:242][][][][][][][][][][][][][LogMessage:ERROR:[sm-Server-02910] Failed to load library 'auth'. Error: Unknown Error]
This issue is caused when the library of the auth scheme being used is set incorrectly.
In the error message, "auth" is not a SM default auth scheme library.
If the auth scheme is not a custom auth scheme, reset the library to the default library, i.e. for basic "smauthdir".
Or
Recreate the auth scheme and change the realm to use the new auth scheme.
