Error invoking Velocity template

[dhina]

We have a user who has issue accessing services using shibboleth IDP(3.1.x).
No other users have this issue. I don't see anything out of the ordinary in
Active Directory for this user.

User is presented with login screen and after authentication instead of
redirected to the service, the user gets an error message from the IDP.
When I checked the logs, the ldap bind works fine and the user was
authenticated successfully.
Here is last part of log where the error happens. Any pointer to
troubleshoot further is greatly appreciated.
