ok,
first I wasn't so impolite (don't know if this word exist !!!!

)
second, I guess that he is able to say if I was rude and to say it! My wish was only to help, if don't want....
second, I can't do a howto for every groupware that exist... can I ????
Ok you want an example, you install egroupware with ldap authentification, you install syncml, sync4j or funambol and outlook/thunderbird...
You can ask the ldap directory with mail client, and the funambol connector sync the new data with the client !!!!
was it unpossible ????
With opengroupware also, and with openxchange too...
the connector are toltec connector, openconnector, cunnector, syncml (funambol, sync4j...), oxtender...
AFAIK it is not possible to store contacts in a user LDAP address book for use with a mailclient and webmail together.
so it is possible !!!!
And if you've got the mail client evolution, Kcontact... under linux, it is a better implementation of the opensource connector and syncml protocol !!!
Enjoy!!!
