Hello,
I will first push out the debug_level = 0x0100. Hopefully this dose get me enough information to solve the problem. Otherwise, I will look into the adcli update wrapper.
I have forgotten to mention that adcli testjoin is still reporting successfully joint despite the error.
Today I got a new report. In this case the computer was reporting "Cannot find key for LC016550$@WAGO.LOCAL kvno 5 in keytab" since 13th of January . And in the keytab file there was a ticket with kvno 4 created at 12th of January. Unfortunately I didn't checked the reported date on the AD side before rejoining the computer. And with the cured log settings a error is only reported if the User is authenticating to computer while connected to the company network. So it might have been in the error state since 12th of January.
