connecting to windows server with SMB2

Quoted 10 lines

I am using kernel version 3.8.13 and windows 7.

The below command works successfully:
Linux#> mount -t cifs //107.109.224.147/sharefolder /mnt -o user=a.sangwan -o pass=xxxx -o vers=1.0 -o sec=ntlm

Other than 1.0, all are fail:
Linux#> mount -t cifs //107.109.224.147/sharefolder /mnt -o user=a.sangwan -o pass=xxxx -o vers=2.0 -o sec=ntlm
[ 0][ 64.276000] Status code returned 0xc000006d STATUS_LOGON_FAILURE
[ 0][ 64.284000] CIFS VFS: Send error in SessSetup = -13

Quoted 2 lines

Tried with sec=ntlmv2/none/lanman/krb5, none of them worked. Help please!!

Did you tries without "sec=" option at all?

If yes, you should set "echo 1 > /proc/fs/cifs/cifsFYI', try to mount and collect dmesg output and send it to the list.

Yes, without sec=ntlm option, I am not able to mount even with vers=1.0

Here it is for the command:
VDLinux#> mount -t cifs //107.109.224.147/sharefolder /mnt -o user=a.sangwan -o pass=xxxx -o vers=1.0

In other mail Benjamin has suggessted to additionally provide -o "domain=" I am wondering why SMB1.0 is success as I don't provide domain in that cas too. Anyway, I will try suggesstion.

Additionally, I am able to connect to samba server (v 4.0.2) from the same machine without giving any -o sec -o domain option and it is success for all 2.0, 2.1 and 3.0 versions.
