Nagios Support Forum

Hi
I'm using Nagios Core 4.4.14
Server version: Apache/2.4.6 (Red Hat Enterprise Linux)
Server built: Apr 28 2023 16:54:19

I enable LDAP authentication using LDAP GROUP to validate access
I put in /etc/httpd/conf.d/nagios.conf
...
AuthLDAPGroupAttributeIsDN on
AuthLDAPGroupAttribute member
Require ldap-group cn=ADGroup1,OU=XXXX,OU=XXXX,OU=XXXX,DC=sedi,DC=group
....

so I enable the user belong to ADGroup1 to get in nagios web interface
In the cgi.cfg I configured
authorized_for_system_information=*
authorized_for_configuration_information=*
authorized_for_system_commands=*
authorized_for_all_services=*
authorized_for_all_hosts=*
authorized_for_all_service_commands=*
authorized_for_all_host_commands=*

In this way all users inside the AD group ADGroup1 are enable to get in Nagios see and operate on all host and services

Now I want to configure a ADGroup2 to see only 3 specific servers

If I work with local user I have to create User1 and I set as contact of these 3 server the User1
In this way when the user1 log in nagios , he is able to see srv1 , srv2 and srv3

NOW I work with LDAP Authentication
What I need to do in order to authorize LDAP group ADGroup2 to see only srv1 , srv2 and srv3

Someone could help me ?

Emilio

in this forum I found
viewtopic.php?t=26488

where are mentioned these directives to set in CGI.cfg file

Are correct ?

authorized_contactgroup_for_all_hosts=
authorized_contactgroup_for_all_services=
authorized_contactgroup_for_system_information=
authorized_contactgroup_for_configuration_information=
authorized_contactgroup_for_all_host_commands=
authorized_contactgroup_for_all_service_commands=
authorized_contactgroup_for_system_commands=
authorized_contactgroup_for_read_only=

Hi @emi65,

I am not familiar with this issue in particular, but is there any reason you cannot try this solution? My recommendation is to give this answer a try and let us know if it doesn't work.

Thank you!

Hi gwesteman

I solved the authorization problem by contact_group using this directive in cgi.cfg
authorized_contactgroup_for_all_hosts=
authorized_contactgroup_for_all_services=
authorized_contactgroup_for_system_information=
authorized_contactgroup_for_configuration_information=
authorized_contactgroup_for_all_host_commands=
authorized_contactgroup_for_all_service_commands=
authorized_contactgroup_for_system_commands=
authorized_contactgroup_for_read_only=

Now I got another problem because the contact are case sensitive and using LDAP windows authentication the problem of the user
name upper or lower case is strong important

I described the problem in github issue
