No, I do have one already running KDC with existing principals stored in 
as standard flat base (I did not well understood the interest of LDAP 
backend when it was set up). I need to import it, rather than for users 
to retype their password again.

I assume that you already have a working LDAP tree.

Yes, that is also what is advertised there:

Thanks, but our setup is a bit more complex (probably three banches, and 
three different kerberos realms). Anyway, adding the missing attribute 
is not the difficult part there :)
