Standalone CIFS local Administrator password change fails
Hello,
I have to install a standalone server on a VNX VG10 Gateway (File OE 8.1.8.121.) butI am unable to connect to standalone cifs server to do the first change of the local Administrator password. Error: Access denied. I followed the following procedure and I am stuck at point 2:
The administrator is unable to manage Local Users and Groups on a standalone CIFS Server using MMC
I press ctrl+alt+del, goto change password:
10.10.10.10\Administrator (10.10.10.10 is ip of cifs server on interface int_vdm_cifsalone)
oldpassword
newpassword
newpassword
klick OK > Error: Access Denied
The cifs server "cifstest" was created on VDM "vdm_vnx_cifs_alone" with the following command:
server_cifs vdm_vnx_cifs_alone -add standalone=cifstest,workgroup=test,hidden=n,interface=int_vdm_cifsalone,local_users
Things I already checked:
Disabled Windows Firewall on local client
Tried Win8, Win7 and even WinXP Clients, same error
Unload and reload of VMD containing standalone cifs
Reboot of both physical datamovers
Any ideas?
Best regards
Robert

Hello,
thanks for the informations. I created a cifs standalone server as described on page 60f. This time I used an ASCII password as writen in documentation during creation progress. (I used 'admin' and 'abcdefg'). The next step is changing the password of 'Administrator' using windows password change (page 70). I still get the same error "Access Denied". CIFS is enabled on the Datamovers.
[nasadmin@VNX01 ~]$ server_cifs vdm01 -add standalone=test1,workgroup=eval,interface=int_vdm_cifsalone,local_users
vdm01 : Enter Password:*****
Enter Password Again:*****
done
[nasadmin@VNX01 ~]$ server_cifs vdm01
vdm01 :
384 Cifs threads started
Security mode = NT
Max protocol = SMB3.0
I18N mode = UNICODE
CIFS service of VDM vdm01 (state=loaded)
Home Directory Shares DISABLED
Usermapper auto broadcast enabled
Usermapper[0] = [127.0.0.1] state:active (auto discovered)
Enabled interfaces: (All interfaces are enabled)
Disabled interfaces: (No interface disabled)
Unused Interface(s):
if=int_replicator l=192.168.1.240 b=192.168.1.255 mac=################
CIFS Server(standalone) test1[eval] RC=2
Comment='EMC-SNAS:T8.1.8.121'
if=int_vdm_cifsalone l=10.10.10.10 b=10.255.255.255 mac=################
Password change interval: 0 minutes

Good day R.Spiess
I am experiencing what appears to be the exact same problem. I only see this using the 8.1.8-37119.ova file however I am successful using the 8.1.0-38015.ova if that's any help. I've posted my issues also and as of yet haven't received any responses.
I have a separate issue after fail-over testing using the 8.1.0 file but maybe that won't interfere with what you have to do.
Hope this helps
If you get your 8.1.8 issue resolved please send me the resolution
Thanks in advance

Hello,
I opened a support case at EMC and the issue was solved.
The behavior happens with VNX File OE8.1.8.119 and above.
A workaround for standalone servers is to change the datamover parameter "cifs.nullSession" to "2" temporary (Default = "0" in OE 8.1.8.119 and 8.1.8.121). All cifs server on the physical datamover are affected. The Administrator password change did work after that. After password change the parameter can be changed back to original value.
Details for "cifs.nullSession" can be found in VNX Parameter Guide 8.1

I did this thing and problem fixed.
1. SSH into your management IP using your nasadmin account
2. To verify the setting, run this:
server_param server_2 -facility cifs -info nullSession -verbose
3. If you need to turn nullsessions back on because it breaks something:
server_param server_2 -facility cifs -modify nullSession -value 1
server_param server_3 -facility cifs -modify nullSession -value 1
4. To turn off nullsessions:
server_param server_2 -facility cifs -modify nullSession -value 0
server_param server_3 -facility cifs -modify nullSession -value 0
