Trying to Get AD Authentication Working With Core 4.4.2

Postby jmichael » Tue Dec 04, 2018 9:28 am

I am trying to get Nagios to authenticate web users logging in to the Nagios URL with Active Directory. I have tried several different things I have found around the web, but still no luck. I am new to Nagios and CentOS7 so any help would be appreciated.

Currently when trying to log into Nagios through a browser when entering my AD credentials the prompt disappears and just keeps re-prompting for credentials. When checking the error logs in etc/httpd/logs I am getting the following error:

[Tue Dec 04 09:16:21.835017 2018] [auth_basic:error] [pid 28139] [client] AH01617: user j*****: authentication failure for "/nagios": Password Mismatch, referer: http://hq0nagios3.***.***/

Attached is what my nagios.conf file looks like.

Try simplifying things a bit in the configuration to see if we can narrow down the problematic config. I was able to get ad/ldap auth working with just 4 additional lines(per section):

Code: Select all
      AuthBasicProvider ldap
      AuthLDAPURL ldap://,dc=acme,dc=local?sAMAccountName?sub?(objectClass=*)
      AuthLDAPBindDN "cn=administrator,cn=users,dc=acme,dc=local"
      AuthLDAPBindPassword password

Is the question mark in AuthLDAPBindDN “CN=Nagios?Connector,OU=IT,OU=Accounts,DC=**,DC=****,DC=***” correct? Seems like it could be a typo.

Attached is a config from a lab machine. Hope it helps.
