hi,

i tried serveral options, but it seems there ist no sles11 support for SMB v2.0.2 or newer.

we need a mountpoint from sles11sp4 to a netapp which has now disabled smb1 for security policy reasons. is there a solution for this?

thx in advance, hannes

SLES11 ships with Samba 3.6, which supports SMBv2, since SLES11SP2.
Please specify the patch and service pack status of your server, how
exactly you’re trying to access cifs, and what error (if any) you receive.

A somewhat older thread, but for reference:

While true for the Samba version, it seems SLES 11 (even patched upto SP4+post patches) misses needed kernel enhancements to support SMBv2.
When connecting to a SMBv2 or v3 capable share SLES 11 will actually connect to it using SMBv1. If the option to connect via SMBv1 has been disabled on the source offering the share, the mount will fail.
