Hello Viktu,

I took another look at the changes and I think what I wrote above is not 
correct. The problem you see can happen when you have AuthBy LSA without 
Group parameter configured. When you do a Group check indirectly from 
AuthBy FILE, Win32::NetAdmin is not loaded when it's needed.

A temporary fix for 4.24 and 4.25 is to edit 
The steps are:

1) Locate this line:
use Win32::Lsa;

2) Add one line just below it so that you have:
use Win32::Lsa;
use Win32::NetAdmin;

Configurations that use Group within AuthBy LSA are not affected. Fix 
for this will be in the next release that will be out soon.

What happens is that Radiator 4.24 changed how Win32::NetAdmin is 
loaded. When AuthBy LSA has parameter Group configured, Win32::NetAdmin 
load is attempted immediately so that its absence can be logged when the 
configuration is loaded. This had the unfortunate effect of breaking the 
indirect use.

Thanks again for reporting this.
