Today I solved my problem on our Ubuntu Server running Cacti 0.8.7d with the LDAP authentication.
After configuring LDAP in Cacti I always got the error message „LDAP Error: Group DN could not be found“ when trying to log in. Searching through the internet showed me this bug report which hinted that this bug would be solved in this version running on the server.
But after some AD browsing and experimenting with older cacti versions I came to the conclusion that PEBKAC can be ruled out. So this bug was still valid for Ubuntu Server 10.04 LTS.
Due to the fact that there is currently no newer version of the Ubuntu Server you can solve this in 2 different ways:
- Download the tar.gz and compile from source
- Download the cacti version included in another version of Ubuntu (e.g. http://launchpadlibrarian.net/56395801/cacti_0.8.7g-1_all.deb)
