Recently our technical staff have setup LDAP bridges allowing different groups to access different parts of our site as well as applying different permissions (edit & view) through roles to which LDAP users are associated. This is working fine and the results are as predicted in terms of behaviour; However, at the front-end (looking at the site from the public access perspective) there seems to have been a performance hit. Each new session (IE7, IE6, Firefox) it takes a noticeable while to load pages (assets to view) after which, being cached, access is no issue.
From a lay perspective the slowness seems to be due to the system checking to see if it should allow access or not… these being public access pages would mean they should be displayed regardless of permission settings. Might this have something to do with the order in which things are set/processed?? Are we missing something in the back-end settings?
Thanks
If you have a single LDAP Server, you should only have one LDAP bridge configured. Without looking at your specific permission setup and design configuration it is difficult to determine why the pages have slowed down since applying LDAP-based permissions.
If you are a Squiz client, I would recommend contacting Squiz Support so that one of them can look at your system to see if there is anything immediately obvious about the configuration that would cause the performance impact.
