[Samba] ldbrename strangeness

[Jochen Eggemann]

Hi folks,

I'm currently playing with a samba 4.1.17 test domain. The classic 
update left me with the usernames as cn. I would like to change the cn 
to the full name of the users.

Doing it by hand is no problem:

ldbrename -H /path/to/sam.ldb "cn=username,ou=users,dc=xxx,dc=yyy,dc=de" 
"cn=Full Name,ou=users,dc=xxx.dc=yyy,dc=de"

Works like a charm.

So I generated a shell script containig the other 200 users in the 
domain. One line per user. Same as above. Running it all I get is:

rename of '"cn=username,ou=users,dc=xxx,dc=yyy,dc=de"' to '"cn=Full' 
failed - ldb_rename: invalid olddn '(null)'

Seems that ldbrename is not getting the olddn. But why? I'm using the 
same syntax. Any ideas?
