Connection to LDAP => Unable to create and modify documents

Hello,

I finally succeed in connecting to a LDAP and with the file
default-virtual-group-bundle.xml I gave the administrator role to one of the
LDAP member.
It seems to work, I can browse every documents with the user but I cannot create
and modify any document...it's a bit problematic for an administrator member :(
I have only read acces, no write acces.

If you have an idea to solve the problem.

Than you.

Damien
