CIFS Client Mount Issues with Windows Server 2008R2
I have been mounting various Windows shares for some time but a new Windows Server 2008 R2 share won't mount like the others.
Server: rp3410, 11.23/64 bit OS
CIFS-Client: A.02.02.02
All patches up to date.
All mounts done in a separate rc3.d script - example:
cifsmount -U username -P password -D domain \
//server/share /mount_point
In my /etc/opt/cifsclient/cifsclient.cfg file, I have modified it to use ntlmv2 encryption (required in our domain):
authenticationMethod = ntlm; # may be "ntlm" or "kerberos"
ntlmEncryptionVersion = ntlmv2; # may be "ntlm" or "ntlmv2"
This has worked for all the other hosts but the 2008 R2 box thinks we are sending just ntlm.
I have tried adding this host as an 'individual' host at the bottom of the cifsclient.cfg file and it will finally work (example below) however that breaks every other server's mounts!
ipAddress = "123.123.123.123";
authenticationMethod = ntlm;
ntlmEncryptionVersion = ntlmv2;
};
I am stuck at this point. Every link to the CIFS Client admin guide is broken.
Any ideas? I have seen some threads that says the current cifs client doesn't support 2008 but I can see that it does.
Thanks for your help.
Regards,
-Brad

Re: CIFS Client Mount Issues with Windows Server 2008R2
Thanks for the link. I have gone over it with my Senior Windows Admin and it only applies to clustered servers. (I have read about SMB clients having issues with clustered servers in other forums.)
This still doesn't explain why I can attach to this server's share when I 'hardcode' it at the bottom of the cifsclient.cfg file. Also, I can't explain why that breaks attaching shares for all the other servers.
Does anyone have a copy of the latest CIFS Administration manual? (As I stated, all HP links to it that I can find are broken.)

Re: CIFS Client Mount Issues with Windows Server 2008R2
BTW, you do not EVEN need to have an rc3 script for you to have your CIFS mounts remount accross reboots. And there relaly is no need to mess around with cifsclient.cfg.
Here's how to mount to CIFS Servers (WIndows or Fellow SAMBA Servers) that will be enshrined in a cifsdb that will persist accross reboots:
cifsmount //cifssrvr.dom.com/sharename /mntpnt -U login -P password -s
The key there is "-s"
Other noteworthy tools you need to manage CIFS Client are:
cifslist -m
cifslist -M
cifsdb (-d) (only on newest CIFS Client)
cifsumount (-d -f)
cifsclient (stop|start)
If things still would nt work despite whatever gyration above, do:
cifsclient stop
cd /var/opt/cifsclient
rm cifsclient.udb cifsclient.pid
cifsclient start
- then do the above cifsmount directive.
Enjoy!

Re: CIFS Client Mount Issues with Windows Server 2008R2
The HP-UX CIFS-Client is based on Sharity and sadly has not been updated since 2007. Sharity 3.7 (April 2009) has some improvements for Windows 2008:
* Kerberos authentication did not work with Windows 2008 servers. Fixed.
* Implemented NTLM2 (not to be confused with NTLMv2) authentication. This improves interoperability with Windows 2008 Server.
http://www.obdev.at/products/sharity/releasenotes.html
So it would be nice if HP could update CIFS-Client...

Re: CIFS Client Mount Issues with Windows Server 2008R2
Brad - please just follow the steps I've outlined above. Your method of having an rc script to ensure the CIFS mounts are persistent accross reboots can be done away with with the steps I've outlined above. Also make sure your Win2K8 environment has all the requisiste hot fixes for CIFS conections.

Re: CIFS Client Mount Issues with Windows Server 2008R2
I assumed it was a old release because software.hp.com says 'Last Update: 31 Oct 2007'.

Re: CIFS Client Mount Issues with Windows Server 2008R2
We installed the hotfix. It did not fix the problem. We spent 3 hours with Microsoft support - no joy. They say that I am not sending a proper version of SMB. We are sending 0.x.x and it needs to be 1.x.x. They verified this via Wireshark and Netmon traces.
I am going to open a Support Case with HP.
Thanks for your help.
