Tivoli software causing lockouts

I have a users accout who keeps getting locked out. I was able to locate the computer passing the bad credentials. It seems everytime tivoli would start a process it's causing him to lockout. For example, the Tivoli orb process starts and the next log is the one listed below. I stopped the Tivoli service for a few days and lockouts stopped. I renabled it and sure enough they persisted. I reinstalled tivoli on the machine to no avail. This is happening on multiple boxes. Has anyone seen this with Tivoli?
