|Summary||0016531: Cannot mount encrypted SMBv3 share from Solaris fileserver but smbclient works fine|
|Description||I have a Solaris 11.4 fileserver running the latest SRU (patch release) 18.104.22.168.0. This server supports SMBv3 with encryption and I can establish an encrypted connection to the share using MacOS 10.14.6 and also using the CentOS 8 smbclient however using the mount command results in failure. |
Problem also exists on CentOS 7.7.
|Steps To Reproduce||Using smbclient: smbclient -e --authentication-file=/root/creds_smb //fileserver_name/Share_Name|
Wireshark shows that encryption and session setup has been successful.
However when using the command:
mount -vt cifs //<ipv6 address>/Share_Name /mnt/share/point -o credentials=/root/creds_smb,seal,vers=3.0
mount error(11): Resource temporarily unavailable
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
I have played around with several cifs mount options (e.g. the authentication type) but none work.

[238890.854588] CIFS VFS: session 00000000a592ea30 has no tcon available for a dfs referral request
[238890.856013] CIFS VFS: cifs_mount failed w/return code = -11
and the Solaris server says:
Oct 3 20:08:07 seraphix-2.achelon.net smbcmn: [ID 997540 kern.warning] WARNING: ../../common/fs/smbsrv/smb2_dispatch.c:smb2_dispatch_message:134:Decryption failure (71)!
|Additional Information||I can WireShark this on request and would share logs if there is a way of sharing them privately with the devs.|
