Graphs Not Displaying - usernames with special characters

Just upgraded from 1.5 to 1.6p6 and noticed with our LDAP users that contain an @ in their username that we cannot open any of the graphs, nor does the popup graph display when hovering over the graph icon in the service table.

If i create a local user without an @ sign the graphs display just fine. Creating a local user with the @ sign the graphs also stop displaying. All other features seem to work just fine.

Update: I Migrated our LDAP accounts to using the sAMAccountName for the user id which only contains a-z and periods and the graphs are again visible and everything is working.

We run into the same Issue.
Is any Solutions for this Problem available?

Aside from moving to usernames without special characters it looks to still be an issue in 1.6p7 with chrome throwing a “redirected you too many times” error page.

This solution resolve my case.

Just edit this file :
/opt/omd/versions/$version/share/pnp4nagios/htdocs/application/lib/json.php

And change the lines 115, 781 and 795

Old: class Services_JSON

New: class __Services_JSON
