Nagios Support Forum

Hello,

We’re using Nagios XI version 5.4.13 and for a couple of weeks now (perhaps since the update on 5/25 to 5.4.13) we’ve encountered an odd problem with our LDAP logins. Inconsistently we’ve been getting “Invalid username or password” even when the username and password is correct.

Log in Failure - Username: Invalid username or password.

https://support.nagios.com/kb/article/a ... n-600.html has some detailed troubleshooting steps for issues like this. Please review and if the problem isn't resolved, let us know what was tried, the results, and any details that may help.
