[Didier Gehéniau]

Thanks for the reply, I will test it and sharpen it en return you the
results.

I sugest I do also a proposal for staticBEgroups

Didier

Hi Didier,

I am awfully busy at the time, so I must be brief.
As far as I know the OpenLDAP Server will store Groupmembership with  
the group record not with the User Record.
The getFEGroups and getBEGroups methods only work with Groupmembership  
which is stored in the user record.

In the OpenLDAP user record you will probably find no reference  
whatsoever about which groups the user belongs to. That's why you can  
not access them via the above mentioned records. To establish the  
groupmembership of a user in OpenLDAP you would have to take the DN of  
the user record and then perform an LDAP search in the group records'  
member attribute to find in which group records the user is registered.  
Those are the groups you want to assign to the fe_user record in your  
TYPO3 installation. The tx_ldapserver class does contain a commented  
out method to perform such a search. It is commented out because it has  
not been tested thouroghly.

Of course, You can include this method in a user class as well an call  
it in a MAP_OBJECT for the field usergroup with the DN as special  
property.

Find the method below.

Sorry that I could not test and document this

Regards

Daniel
