[Samba] Using Samba and Rational ClearCase Tools

[Sharpe, Annik A]

Hello,
We are using Samba to connect our ClearCase server to the Windows environment. Our original configuration was one server hosting all our VOBs and Views. We have Samba configured to allow mapping of shares to our ClearCase Windows Clients. Everything was working fine. Now we have set up a second server to host all our Views separate from the VOBs. So we have a View server and a separate VOB separate. When we setup the View server we installed Samba on that server, copied the config file from the original setup to the new server and the only configuration change made was in the Global parameters, the NetBios Name to be the new server name.

We are able to map a network drive to our new server. We are able to create a View on the UNIX server, region synchronize on the Win Client side and mount a VOB. However when we try to create a new file we get a window stating "Access Denied." If we try to check out an existing file we get an "Error checking out {filename}. Unable to update view {viewname}: Permission Denied. Unable to check out {filename}."

We are able to complete all these steps within the UNIX environment, we are only having problems from the Windows environment and so we are assuming it has to do with our Samba configuration.

We already know groups, permissions are okay. We've checked credmap against the two servers. Any ideas?

Thank you,

If you already know groups, permissions are okay then that means that
you've checked all the logs, right? syslog as well as all samba logs -
especially the log for the ip/computer trying to connect.

This is usually caused by a permission problem.

Did you copy username.map from the VOB server to the View server?

What are the exact details in the view_log on the client?
Is there anything in the error_log?

What is the ALBD Account? Is there a corresponding UNIX account?

Do you realize that performance of views through Samba will probably
be 50-200+% worse than a local view?

If you increase the Samba debug level to 3 and repeat the operation,
what is in the Samba log?

Do you have 'log file = /usr/local/samba/var/log.%m' in your smb.conf?
This will make it easier to debug.

Hi Eric,
Thanks for your help. We actually figured out our problem. We had a variable set to "Read Only" which was preventing us from getting to our data.

Thanks again for your help and prompt response!
