Monitoring Error: Cannot complete login due to an incorrect user name or password


I’m getting the following error for a few service modules:

Possible precedence issue with control flow operator at /usr/share/perl/5.20/VMware/ line 2332.

Error: Cannot complete login due to an incorrect user name or password.

The error seems obvious in a sense that some user that is being used to get the data that icinga displays has changed password or user name but to my knowledge nothing of the sort happened.
From a bit of searching I found out that icinga users should change passwords every 90 days or something but I looked at the users and none of them are locked.
Also the user icingadmin in AD is not locked nor the password expires.

I’m not the person that setup the icinga server and have no clue how to troubleshoot it further.

Any help will be greatly appreciated.



the output originates from the check and executed plugin itself. In this case obviously check_vmware. Nothing related to Icinga Web itself.

In order to troubleshoot further, extract the executed command line and manually test what’s going on. This is described in the troubleshooting docs.


Hi Michael!
Thank you very much for your reply.
Can you tell me where that command is and how to extract and test it?
I have no clue about how these things work.
Sorry for taking up your time.
