I have Nagios installed with traditional configuration files. I have created some contact groups and assigned them to hosts. For web UI I'm using check_mk. And here's the question: Check_mk supports showing hosts/services based on contact group membership. But I can't use the Nagios contact groups in check_mk. (Result should be that if person XYZ is logged in, he see only hosts and services assigned to him.) My users are in LDAP (I'm using check_mk login form, not apache authorisation). I can't find any information about this in documentation so if someone have experience, please tell me how this works. The problem is that I cannot let everybody be admin and receive all alerts...
