Can't create group quota

Jonis

Hi.

 

I'm trying to setup our new FAS2750 (ONTAP 9.6), but I'm having some troubles with quota and groups. Our local netapp support/partnet has installed and configured our system and joined to our domain (called fea-rp.local). Everything is fine, we can create CIF's chares's, set permissions (users and groups) and login into our ONTAP using AD users.

Now I'm tryng to create a qtree and then create a group quota for this qtree, but it doesn't work. Always get this error:

 

Quota creation failed on '/vol/vol_dados_fearp/qtree_grupos'
Reason : Failed to create quota.
ONTAP API Failed: Group name sti not found. Reason: SecD Error: object not found.

 

'sti' is group name. I've also tried with "FEA-RP\Sti", still not working, but different error:

Quota creation failed on '/vol/vol_dados_fearp/qtree_grupos'
Reason : Failed to create quota.
ONTAP API Failed: Target for a group quota cannot be a Windows account.

 

Note that we only have a group salled 'sti', not an user.

We need to check the secd logs, could you give us the output of this command


From clustershell:

 

::> event log show -event secd*


Question to you:
Do you have iSCSI and NAS interface in a same vserver where this share/qree is created ?

 

Will need output of this:
::> network interface show -role data -vserver <vserver_name>

Jonis

Sure!

Question to you:
Do you have iSCSI and NAS interface in a same vserver where this share/qree is created ?

No. iSCSI and NFS use separeted interface/VLAN each. CIF's is another thing: I have two different VLAN's for access: one is network 10.107.205.0/24 (which is the same of management interface, but uses 'data' ports and not management port) and other is 1.2.3.4 (this one is a valid IP). My AD is reachable by this second option, a valid IP. My ONTAP has gateway configured only for this network (valid ip), none of invalid networks/other has gateway defined.

Note: I'm planing to use this qtree/cif's/volume with both windows and linux clients/servers.

Ok, I found that CIF's doesn't use the same connection that management interface uses for auth. I need to configure LDP Client in my SVM. 

So, I've setup my LDAP configuration and tested with "vserver services name-service ldap check -vserver FEARP_01". My connection looks fine now, but still not getting account/groups objects. I found this article:  https://kb.netapp.com/app/answers/answer_view/a_id/1029829/~/how-to-troubleshoot-ldap-issues-in-clustered-data-ontap-

 

The problem is that I my ONTAP doesn't have command 'getxxbyyy'...or better, doesn't have any 'get<anythin>' command, so I can't test query. Is there any other way, or what am I missing?

I would like to test my LDAP query from ONTAP....I think it's a permission problem now. Also, ONTAP does recursive queries while looking for accounts/groups?

I'm using my first level as BaseDN.

For mixed environment (win/unix) you will need to set up mapping.

 

Test connection:
[set diag]
:*> diag secd authentication show-creds -node <node> -vserver <vserver> -unix-user-name xxx


FAQ: Understanding name-mapping in a multiprotocol environment

Note that you can use name mapping only for users, not for groups. It is not possible to map CIFS users to a group ID (GID), or UNIX users to a group in the Active Directory (AD). Similarly, it is not possible to map a GID to a group or a user in AD, or an AD group to a UNIX UID or GID.

Ok I've changed to NTFS to simplify things.....but still with same problem.

 

I've tried both test commands, only one works:

Clt_FEARP_01::*> diag secd authentication show-creds -node Clt_FEARP_01_1 -vserver FEARP_01 -win-name jmaurin

 UNIX UID: root <> Windows User: FEA-RP\jmaurin (Windows Domain User)

 GID: daemon
 Supplementary GIDs:
  daemon

 Primary Group SID: FEA-RP\Domain Users (Windows Domain group)

 Windows Membership:
  FEA-RP\Domain Users (Windows Domain group)
  FEA-RP\Domain Admins (Windows Domain group)
  FEA-RP\StorageAdm (Windows Domain group)
  FEA-RP\brigada (Windows Domain group)
  FEA-RP\sti (Windows Domain group)
  FEA-RP\Administradores Locais (Windows Domain group)
  FEA-RP\AppVAdministrators (Windows Domain group)
  FEA-RP\radius (Windows Domain group)
  FEA-RP\AppVUsers (Windows Domain group)
  FEA-RP\funcs (Windows Domain group)
  FEA-RP\reservas (Windows Domain group)
  FEA-RP\Aplicacoes (Windows Domain group)
  FEA-RP\Enterprise Admins (Windows Domain group)
  FEA-RP\Schema Admins (Windows Domain group)
  FEA-RP\Denied RODC Password Replication Group (Windows Alias)
  Service asserted identity (Windows Well known group)
  BUILTIN\Users (Windows Alias)
  BUILTIN\Administrators (Windows Alias)
 User is also a member of Everyone, Authenticated Users, and Network Users

 Privileges (0x22b7):
  SeBackupPrivilege
  SeRestorePrivilege
  SeTakeOwnershipPrivilege
  SeSecurityPrivilege
  SeChangeNotifyPrivilege

This command returns the same error while I try to add quota for user:

Clt_FEARP_01::*> getxxbyyy getpwbyname -node Clt_FEARP_01_1 -vserver FEARP_01 -username jmaurin -show-source true
  (vserver services name-service getxxbyyy getpwbyname)

Error: command failed: Failed to resolve jmaurin. Reason: Entry not found for "username: jmaurin".

I'm not sure what's wrng, since first command could find my user object and second command can't. I think it isn't a connection problem (with my AD), right?

 

Ontapforrum

ok. Could you give us this output:

 

::>vserver cifs options show -vserver vserver_name
::>vserver services unix-user show -vserver vserver_name
::> vserver name-mapping show -vserver vserver_name -direction unix-win

Solved!

I have mapped all win-users to 'pcuser'. This is right?

Also, why I need to map, since I'm using only NTFS in security of my volume?

Ontapforrum

Solved = hurray 🙂

 

I was just reading this when you replied:

https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-vsmg%2FGUID-A019B690-EB03-43C2-B755-1F265EC9E986.html&lang=en

 

The user-mapping parameter is set to "on" in the quota rule for the user.

 

I agree, with NTFS security-style, it should only need mapping of unix-user to Windows (bydefault unix-user 'pcuser ' is defined in 8.3 later)..I am thinking now.
