This was a problem with the way calendar handles participants, was fixed in stable cvs. In HEAD this will be a non issue.

Hi ya'll,

each page load makes an ldap connect/search to get the first and last name of the actual user.

These information should be stored in the session.

But I'm still suprised that it takes 10-15 sec for authentication.

2600 isn't so much.

Cheers, fips

Hi minddog

we have something like 1200+ users in LDAP and ~120 groups. from 20 sec delay for admin user accounts , we manage to get "only" 4 sec by tweaking the openldap database (not using the default cached keys, but adding some of them). But I guess that you already have such optimisations.

For authentication I'm very surprised, it's don't take more than 2 or 3 seconds here, and then things are going relatively fluently.

When we need to wait a long time, it's for exemple when you need to get all people in the same page (like in sitemgr ACLs) or users accounts management. But switching apps is not impacted.

Could you be more precise in the king of configuration you are using, kind of server, overall system etc ... just to get an idea on what's happening ?

Thanks.

I assign it to fips, but not sure if this is a "real" bug.

Cheers,

Caeies

phpgroupware becomes slower by an increase of users inside ldap.

A real world installation with 2600+ users causes a 10-15 second delay when authenticating, switching apps, performing actions.
