I would really appreciate some help figuring out why one of my students has
"disappeared" from the user list, and what to do about it. I'm
using Samba3 on
Fedora; the client machines are running WinXP. The system has been up and
running since the beginning of September.
Today one of my 4th-graders was unable to log on; she didn't read the error
message carefully, so she couldn't tell me exactly what happened. (This
student
has logged on successfully many times before.)
(The only change to the logs below is the students' names.)
So I tried to change her password so I could test her logon:
[root@zeus ~]# smbpasswd student1
New SMB password:
Retype new SMB password:
Failed to find entry for user student1.
Failed to modify password entry for user student1
I did not find her listed anymore in the linux users.
I used pdbedit to check her entry:
[root@zeus ~]# pdbedit -Lv student1
Unix username: student1
NT username:
Account Flags: [U ]
User SID: S-1-5-21-1185660-1660059191-2813172890-2076

...and compared it with the entry for a student who successfully logged in about
the same time:

I noticed that the unsuccessful student had a "kickoff time" entry
(with a
peculiar date, same as the "Password must change" date), but the
successful
student had only a "0" in the "kickoff time" field.
The log file for the machine she attempted to log onto contained these entries
for the time she tried to log in:
