AIX NIM Client Move
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 show you how to move NIM clients from one NIM environment to another. This page is for AIX 5.3 and AIX 6.1.

I was in the situation that I created a new NIM environment to replace the old NIM environment. I didn't want to follow IBM's documentation on how to move NIM clients from one master to the other so I created my own procedure. Steps are pretty simple:
- Remove the NIM client from the old master
- Add the client to new master
- Check the niminfo file
Sharepoint User Domain Migration using Stsadm

While doing an AD migration we ran into a very annoying error while trying to migrate the sharepoint users. If you are a little bit familiar with Sharepoint you would know that all users are known by a unique id in the sharepoint database, and also by their domain. Now if a user changes from his or her domain, he or she would lose access to their sharepoint data. Even if you'll use the SID history option. That is of course not what you'd want so there is a migration option to change all ownerships from one use to another, stsadm -o migrateuser. However, while testing this command we ran into some errors and it took us months to find out what went wrong. It turned out users were connected to orphaned sites, so we had to clean up these orphaned sites before we could migrate these users. In this article I'll show you everything I can remember from these errors and issues, the fix, the migration scripts and some information to collect permissions from sharepoint.

While doing an AD migration from AD 2003 to AD 2008 I came across an issue with an application. This application was already installed on a server in the new domain, however, before the migration the users would use their accounts from the old domain. After the migration we found it was impossible to log on from a client server. Only if we would install the client on the application server itself logging using the new accounts would work.
Eventually we found the error in one of the logfiles, and with that, the solution as well.
Just for reference sake, the name of the application was Algo Collateral 5.2.1
Sendmail Security Quick Fixes
Summary: As one of the most enduring Unix applications and one of the most ubiquitous, sendmail has been the target of numerous attacks over the years – from buffer overflows to denials of service. And, even with constantly improved security, sendmail can be prodded into a state of improved security through a number of quick fixes that any sysadmin can make to reduce the vulnerability of their sendmail servers.
