I have confirmed this observation on SuSE10 (x86), and Solaris 8. Samba 3.0.21c and 3.0.22. In a nutshell, I'm using Samba 3, 'security = ADS', MIT Kerberos, etc. Everything seems to be functioning fine on the majority of my test machines, including the use of 'winbindd' in 'netlogon proxy' mode. I also utilise a logical IP interface for Samba's sole use (and use 'bind interfaces' to force the issue) as I don't want to interfere with the UNIX server's existing Kerberos config and principles. This also lends itself to a clustered environment, etc... But, when testing 3.0.22 on a new machine I started to observe wbinfo and winbindd failing with a 'STATUS_BUFFER_OVERFLOW' error. The only difference that I could see was that this server had a fairly long hostname/NetBIOS name, and it seemed to get truncated in various logfiles. Reducing the name length, and then re-joining the domain fixed the situation. No more errors, and 'wbinfo -t' succeeds... My smb.conf looks like this: [global] server string = SYD-WILLIAMC-CIFS Linux Samba Server netbios name = SYD-WILLIAMC-CIFS workgroup = DBG ; wins server = sydeswwnp1.au.db.com, sineswwnp1.sg.db.com security = ADS realm = DBG.ADS.DB.COM use kerberos keytab = No password server = * encrypt passwords = Yes client use spnego = Yes client ntlmv2 auth = Yes client lanman auth = No client plaintext auth = No use spnego = Yes lanman auth = No ntlm auth = No disable netbios = Yes dns proxy = No client schannel = Auto server schannel = Auto client signing = Auto server signing = Auto idmap uid = # Netlogon proxy mode only idmap gid = # Netlogon proxy mode only winbind enum users = No winbind enum groups = No deadtime = 5 hostname lookups = Yes hosts allow = localhost, 10. hosts deny = ALL interfaces = localhost, syd-williamc-cifs.au.db.com bind interfaces only = Yes ; guest account = pcguest log level = 5 log file = /var/log/samba/log.%M max log size = 1024 socket options = TCP_NODELAY IPTOS_LOWDELAY nis homedir = No hide dot files = Yes ; include = /opt/DBsamba/etc/smb.conf.%M include = /opt/DBsamba/etc/smb.conf.standard ; username map = /opt/DBsamba/etc/smb.map A google for the 'STATUS_BUFFER_OVERFLOW' reveals a handful of similar reports, but no definitive fix. And this maybe a red herring, but where the information was available in the posting it looked like they all had suspiciously long NetBIOS names configured?

nsswitch/winbindd_ads.c:trusted_domains(908) trusted_domains: Could not open a connection to DBG for PIPE_NETLOGON (STATUS_BUFFER_OVERFLOW)
Windows does not allow computer names longer than 15 characters. So I'd be inclined to reject this bug report as invalid. We might add a check for that restriction when joining the domain. Jerry, what do you think? Volker
Actually, in the absence of winbindd, smbd throws the same error when it tries the 'netlogon' stuff. Which I guess makes sense. Shortening the NetBIOS name definitely fixes the issue, and I'd agree that the fifteen character limit should be checked for and at the very least warned about... But, in this day and age why we still need to observe such draconian limits is beyond me. Maybe someone in Redmond could shed some light on it?!... Will.
Will, if we addd a check in testparm to whine about long server names, would that satisfy things from your perspective?
I think that at the very least testparm should flag the issue. But, seeing that things actually break (any and all interaction with 'netlogon') if you exceed a 15 character NetBIOS name then should Samba completely disallow them and refuse to start? A terminal error condition? A quick Google for the symptoms of this 'bug' reveals many similar problems, and I'd bet that they're down to a similar misconfiguration. Will.
*** Bug 2371 has been marked as a duplicate of this bug. ***
With r15137 we refuse to join if our name is too long. I think this fixes this bug sufficiently well. Volker
OK, so the proposed 'fix' will prevent names >15 characters. But, is this really a valid restriction in a 'modern' environment without NetBIOS? Is it the Active Directory domain controller that's throwing the netlogon error back to Samba? If so, then fine this fix works. But, equally is this an arbitrary, historical limit imposed by Samba code in the belief that it's still required in all circumstances? Thanks for looking into this! Will.
Yes, this still applies to modern environments. We always need to be able to fall back to NTLM authentication in case Kerberos fails for some reason. And there are really many reasons, the most likely is inconsistent server names. And NTLM domain authentication fails with longer machine account names. Volker
Volker, I've just had a look at the 3.0.23pre1 source, and I guess that this code added to net_ads.c is your NetBIOS name length check? if (strlen(global_myname()) > 15) { d_printf("Our netbios name can only be 15 chars long, \"%s\"" " is %d chars long\n", global_myname(), strlen(global_myname())); return -1; } Looks OK, but could I suggest two things? Firstly, the hardcoded '15' could perhaps be defined somewhere and given a name? Although that having been said, it's hardcoded elsewhere in the source too... Second, the error string is a little deceiving? Perhaps it should really say 'Our netbios name can be at most 15 chars long'? The above can be read to mean that the name must be exactly 15 characters long?!... Anyway, thanks for this, Will.
