[Samba] Oplocks
Hello,
I'm using the Samba server 3.0.33 that exports volume from a GPFS. The GPFS
strongly dislikes unlinking files that are locked (resulting in permission
denied) using fcntl F_SETLEASE.
It seems that the Samba *sometimes* tries to unlink a file that is oplocked.
Why? Is this a bug? Why it does not happen always but only sometimes? I have
strace logs showing:

In theory, what you describe should not happen, at least not with current Samba. I'm not sure about ancient 3.0.33, but with current Samba this can only happen if you run Samba on the same file system from two different nodes. This is an invalid configuration, you need to use the clustered Samba with ctdb for that. I have only one samba server for a GPFS volume so I should not need clustered Samba.

[Samba] Backup files from Windows application
Hello, I'm using sama 3.0.24 on linux machine that serves a share for a windows client. When editing a file on samba, using MS Word I can see there are severals (probably) backup files. ls looks like this: Dotaznik1.doc ~$taznik1.doc ~WRD.tmp ~WRD0001.tmp ~WRD0002.tmp ~WRD0003.tmp ~WRD0004.tmp These files do not disappear after I quit the Word. This does not happen if I edit the files locally, the backup files are created but deleted after application quits. Is it something samba related? the share looks like: [uvt] comment = UVT For testing browseable = yes writable = yes path = /mnt/export2/smb/UVT guest ok = no create mask = 0644 directory mask = 0755 public = yes valid users = some users -- Lukáš Hejtmánek -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
[Samba] Samba authentication
Hello, I wonder whether there is a way to authenticate samba against NTLM2 enabled radius server without using encrypt passwords = no. I really have no other option than this. My situation is as follows. I have an organization that runs Microsoft Windows Server 2003 which is used as AD. This AD shares passwords with many information systems in our organisation and I would like to use these passwords also for samba users. Administrators of AD disagree to add my samba server to their AD. No way here. They agree to export LDAP (without passwords), Kerberos or Radius and possibly other services but not AD itself. Is there a way to authenticate my samba against their authentication service? If there is no way per-se, would it be possible to modify windbindd to authenticate via NTLM2 against the Radius server instead of AD? -- Lukáš Hejtmánek -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
