samba - Nov 2015 - Problem setting password: : failed to pull old supplementalCredentialsBlob: NT_STATUS_BUFFER_TOO_SMALL

Hello,

I am stuck with a error when setting password for a couple of specific 
users. This error makes impossible to set the password for the affected 
users.

In Windows I get an operation error but the samba-tool output is more 
informative:


samba-tool user setpassword user2 --newpasswordNew Password:
ndr_pull_error(11): Pull bytes 2 (../librpc/ndr/ndr_basic.c:103)
ERROR: Failed to set password for user 'user2': (1, 
'setup_supplemental_field: failed to pull old 
supplementalCredentialsBlob: NT_STATUS_BUFFER_TOO_SMALL')
File "/opt/samba4/lib/python2.7/site-packages/samba/netcmd/user.py", 
line 587, in run
username=username)
File "/opt/samba4/lib/python2.7/site-packages/samba/samdb.py", line
484,
in setpassword
self.modify_ldif(setpw)
File "/opt/samba4/lib/python2.7/site-packages/samba/__init__.py", line
235, in modify_ldif
self.modify(msg, controls)

Someone knows how to workaround this error?.

Hi,

I don't know much that tool but I would have expected
"--newpassword="
needs some password.

Ex:
samba-tool user setpassword user2 --newpassword=1NewPass
or just
samba-tool user setpassword user2

The first one would be to avoid interactive behaviour (no password asked,
you have already given it to the command)
The second would be to start that command in interactive mode : no password
given on command line, the command ask you for a password.

Perhaps I'm wrong, perhaps you tried to set a blank password for that user
(NT_STATUS_BUFFER_TOO_SMALL as an error seems to mean the password you gave
is too small for your password rules).
In that case just try to set a complex password to your user when the
command ask you for a password.

Sounds like a corrupt DB to me.  How did it get there?

If this is corrupt, then there is likely more trouble in the DB, we
have never seen that before.

Thanks for your answer, Andrew Bartlett.

We had abandoned this problem but if you want I can request files for debug.
