Argh! I've got a problem with NIM!

Yes, I am testing it for you ;-)

I installed my new NIM server last week, together with the security patch. Meanwhile, the new 7.3 TL4 became available with support for YubiKey! Mmm. I want it! Of course, I updated my freshly installed NIM to AIX 7.3 TL4. Oops, it stopped working!
