I also tried this troubleshoot in case it's relevant, I added this to httpd.conf file, and when opening Observium in a browser, Apache prompts for authentication, a FreeIPA user can authenticate successful, but then Observium auth fails.

Hi Richard, the base dn is dc=us,dc=example,dc=com. Just for the record, the host where Observium runs is also FreeIPA client, and I'd like to login to Observium as this person:

Hi Zarko
What is the base dn of the FreeIPA install (it’ll be something like dc=example,dc=com)?
What configuration do you currently have for LDAP in your config.php?

Zarko, This configuration works for us. Do a find and replace on "dc=domain" and make it your domain.

Hi there
I want to be good citizens and check first Archives but this link was not found. http://postman.memetic.org/pipermail/observium/
Anyway, I try configuring Observium (*Observium CE*0.16.1.7533) to authenticate via LDAP, it's FreeIPA server using 389 Directory Service for ldap service. Unfortunately I can't make it to login.
- The config.php reads:
$config['auth_ldap_version'] = 3; // v2 or v3 $config['auth_ldap_server'] = "ca-ldap01.x.com http://ca-ldap01.x.com/"; $config['auth_ldap_port'] = 389; $config['auth_ldap_starttls'] = OPTIONAL; $config['auth_ldap_prefix'] = "uid="; $config['auth_ldap_suffix'] = ",cn=users,cn=accounts,dc=us,dc=x,dc=com"; $config['auth_ldap_attr']['uid'] = "uid"; // LDAP attribute containing user login name $config['auth_ldap_attr']['uidNumber'] = "uidNumber"; // LDAP attribute containing numeric user ID $config['auth_ldap_attr']['dn'] = "dn"; // LDAP attribute containing user's DN $config['auth_ldap_attr']['gidNumber'] = "gidNumber"; // LDAP attribute containing group id number $config['auth_ldap_objectclass'] = "posixaccount"; // objectClass to filter out valid users, use * for all objects under ldap_suffix tree $config['auth_ldap_groupmemberattr'] = "memberUid";
