[Samba] Another problem with samba4 classicupgrade

[Hervé Hénoch]

Hello

I've used the following command :

      /usr/local/samba/bin/samba-tool domain classicupgrade
    --dbdir=/root/samba3/ --realm=sc.isc84.org  /root/samba3/smb.conf

And the following error :

...
Importing Account policy
Importing idmap database
Cannot open idmap database, Ignoring: [Errno 2] No such file or directory
Exporting posix attributes
*ERROR(<type 'exceptions.KeyError'>): uncaught exception - 'No such element'

   File "/usr/local/samba/lib/python2.7/site-packages/samba/upgrade.py", 
line 543, in get_posix_attr_from_ldap_backend
     return msg[0][attr][0]*

Any idea ?
