PAM login with v1.0.1 not authenticating, no error message

[trel]

I am trying to use the cloud browser. We authenticate using PAM.
Works fine with 1.0. PAM itself works with the command line client
and also when I test directly with PamAuthCheck.

With version 1.0.1 it just repaints the login screen without any error
message when I try to log in. Same with Safari and Chrome. I don't
see any corresponding error message in catalina.out for Tomcat.

The iCAT server logs:
