Fix: After ADMT Migration Users Cannot Logon - Profile Errors - Kerberos - MaxTokenSize

After migrating AD User Accounts between Active Directory Domains, and enabling the SID history, some users were not able to logon anymore. This is because the Kerberos token size is too big so users cannot access their profile anymore, cannot access their network mappings and policies are not applied anymore.
I will discuss the quick fix here, and give some detailed background information and additional fixes.

In this article I'll show the steps and script to manage team membership based on being a member of an Active Directory security group. I'll create two Azure Enterprise Applications, a script and an Azure DevOps Server pipeline. How fun.
AIX Home Directory
Summary: ALthough AIX is by now on version 7.3 I find these old pages so fascinating I decided to keep them. On this page I'll tell you how to automatically create a home directory when a user logs in using SSH. This page is for AIX 5.3 and 6.1.

Under normal circumstances you would use the PAM module pam_mkhomedir.so to create a home directory when it not exists and a user logins. This does not work using SSH because this is considered a security breach. This article is about the autocreation of a home directory when users login using SSH. Because the pam module doesn't work anymore we use the “make_home_dir” program from TrustSec.
Note: The recommendations used here are mostly from the readme, this readme was however created for linux so a few commands didn't work. The commands used here are for AIX.
