Dear list,
I'm failing to terminate a session of a no longer existing NIS user.
Situation
-------------
User accounts are imported via NIS by the X2Go server ('lucas'). Home directories are mounted via NFS.
Recently, an account ('prakti03') was deleted on the NIS server, and the corresponding home directory purged from the file server, while there was still a X2Go session running on the X2Go server.
What I did
---------------
root at lucas:~# x2golistsessions_root
31436|prakti03-56-1486112626_stDLXDE_dp32|56|lucas|S|2017-02-03T10:03:46|29549c54420137ca42be3121da1dddb4|10.10.6.48|61014|61015|2017-02-10T15:04:53|prakti03|4674671|61016|
root at lucas:~# /usr/bin/x2goterminate-session prakti03-56-1486112626_stDLXDE_dp32
root at lucas:~# echo $?
0
root at lucas:~# x2golistsessions_root
31436|prakti03-56-1486112626_stDLXDE_dp32|56|lucas|S|2017-02-03T10:03:46|29549c54420137ca42be3121da1dddb4|10.10.6.48|61014|61015|2017-02-10T15:04:53|prakti03|4676057|61016|
What I observe afterwards
--------------------------------------
/var/log/auth.log is flooded with entries like this (roughly 70 blocks per minute):
Apr 2 07:00:00 lucas su[9223]: No passwd entry for user 'prakti03'
Apr 2 07:00:00 lucas su[9223]: FAILED su for prakti03 by root
Apr 2 07:00:00 lucas su[9223]: - ??? root:prakti03
Question:
--------------
How can I make X2Go 'terminate the session'? ('Session' in quotation marks, as there are no processes with the user's (numerical) UID running anymore.)
Thanks in advance,
Holger
