Summary0016531: Cannot mount encrypted SMBv3 share from Solaris fileserver but smbclient works fine
DescriptionI have a Solaris 11.4 fileserver running the latest SRU (patch release) 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 ReproduceUsing 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

results in:
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.
Syslog says:

[238890.852369] CIFS VFS: failed to connect to IPC (rc=-11)
[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 smbcmn: [ID 997540 kern.warning] WARNING: ../../common/fs/smbsrv/smb2_dispatch.c:smb2_dispatch_message:134:Decryption failure (71)!
Additional InformationI can WireShark this on request and would share logs if there is a way of sharing them privately with the devs.
