Hi all,
After the latest Windows May update, some users are no longer able to log into IFS Apps 9. They are receiving an error stating that the login service is unavailable. After some investigation, we found that this is caused by Microsoft's hardening of Kerberos Authentication. We are currently in the process of migrating to IFS Cloud, but we still need to use Apps 9 until January 2027.
We managed to temporarily resolve the issue by adding a registry key, but this workaround will only work until the June update. After that, we either have to find a permanent fix or stop installing updates.
Has anyone else encountered this issue, and if so, how did you fix it? The only long-term solution we can think of is creating a new account and a new keytab file, and then reconfiguring IFS Apps 9 to use them. If anyone has an easier workaround, we would love to hear it!
