+++ This bug was initially created as a clone of Bug #45186 +++

After updating to errata 129, we received several customer reports with the nagios message: UNIVENTION_NSCD NRPE: Unable to read output



+++ This bug was initially created as a clone of Bug #42812 +++

After installing a docker appbox app, the Nagios check for nscd shows a warning:

Comment 1 Felix Botner univentionstaff 2017-08-11 12:40:03 CEST 
To complete Bug #45186, we should remove the nagios client from UNIVENTION_NSCD and add the client to UNIVENTION_NSCD2 in 30univention-nagios-client.inst during the update to 4.2 (at this point we can be sure UNIVENTION_NSCD2 exists)
Comment 2 Ingo Steuwer univentionstaff 2020-07-03 20:54:18 CEST 
This issue has been filed against UCS 4.2.

UCS 4.2 is out of maintenance and many UCS components have changed in later releases. Thus, this issue is now being closed.

If this issue still occurs in newer UCS versions, please use "Clone this bug" or reopen it and update the UCS version. In this case please provide detailed information on how this issue is affecting you.
