When other than admin user tries to login, the following error msg is displayed in the browser:

Software error:Use of uninitialized value in string eq at /xxx/lib/TWiki/Users/TWikiUserMapping.pm line 471.

If admin user attempts to login, everything goes just fine.

After several reinstallation, problem remained permanently.

I have another installation working fine on another server with exactly the same config as below.
