I have installed 32-bit Kerberos 3.2.2 from Secure Endpoints and 32-bit OpenAFS 1.5.78. Each user runs commands like below when they login to Windows.
kinit -5 -r 7d -k -t C:\users\%krb_user%.keytab %krb_user%@MYDOMAIN.NET
aklog -d -c MYDOMAIN -k MYDOMAIN
net use x: \\afs\mydomain\users\%afs_uid%\MyShares
This works fine up to about 35-40 Windows users, then the aklog starts to fail and the Kerberos kinit starts failing getting tickets. The server pretty much grinds to a halt despite low CPU and memory usage. Either rebooting the server or killing all the krbcc32s.exe processes and restarting the OpenAFS client service fixes the issue. I am not sure if the AFS client service or the kerberos processes are the cause of the problem. Any suggestions to help fix this issue would be appreciated.
