Checking up-state of LDAP-protected domains

Service Monitoring
1

Good morning everybody,

I need your help in finding a fitting approach for checking the up-state of several web-adresses behind LDAP-authentication.

Up until now (before LDAP was set up for the websites in question) I used the simple check_http plugin for this use case, but now I am getting warning-states because the websites are returning 401 Unauthorized answers.

Is there a good plugin to fit my use case? My first quick searches couldn’t find any and I am not an LDAP specialist myself, so maybe somebody else could point me to the right direction.

Best regards
Daniel

Hi,

Do you want to get the passwords from LDAP or just check the websites with a user/pass ?

Hi,

I’d like to check the websites with a valid user/pass combination.

Hi,

Check_http has a lot of options, so take a look at the documetation .

Specifically, you could use something like:

-a, --authorization=AUTH_PAIR
   Username:password on sites with basic authentication

which in ITL translates to:

               "-a" = {
                        value = "$http_auth_pair$"
                        description = "Username:password on sites with basic authentication"
                }

That should get you started

Cheers,
George

Thank you very much for this hint, I will do some research and come back to this thread.

Thank you very much @gkoutsog, it did the trick.

I could continue using check_http passing the following parameters, in case anybody wants to reproduce this:

./check_http -H hostname -I 00.00.00.000 -S -u '/url' -a 'username:password'

Notice that it is just the hostname, not the actual FQDN which needs to be passed (it can of course be omitted as well).
