 |
|
I've got samba 3.0.22 with winbind trying to authenticate to Active Directory. I've done this before but haven't done it for a while. I've set everything up and joined the domain but trying to log with a domain account fails and I get the following error: | Code: | pam_winbind[30274]: request failed: STATUS_BUFFER_OVERFLOW, PAM error was 4, NT error was STATUS_BUFFER_OVERFLOW
pam_winbind[30274]: internal module error (retval = 4, user = `someuser')
login(pam_unix)[30274]: check pass; user unknown
login(pam_unix)[30274]: authentication failure; logname= uid=0 euid=0 tty=tty1 ruser= rhost=
login[30274]: FAILED LOGIN (1) on `tty1' FOR `someuser', Authentication failure
pam_winbind[30274]: request failed: STATUS_BUFFER_OVERFLOW, PAM error was 4, NT error was STATUS_BUFFER_OVERFLOW
pam_winbind[30274]: internal module error (retval = 4, user = `someuser')
login(pam_unix)[30274]: check pass; user unknown
login[30274]: FAILED LOGIN (2) on `tty1' FOR `someuser', Authentication failure |
The pam module is obviously suffering a buffer overflow and that is why the auth is failing. What I don't know is why this is happening or how I can fix it. Does anybody know anything about this or how I can make it work again. I'm sure that at the beginning of the year I got this working with 3.0.22.

You ever get this working? I'm seeing this now on one of my new servers.

nope, didn't get time and nobody had anything helpful to say.
I did see something on the net which said that it's gcc's fault for producing faulty P4 binaries and that using pentium3 in march instead would make it work. Haven't tried yet.
If that works for you pls post back so I know.
