Hello All,
We recently cut over from a FAS to an AFF running 9.8P1. Serving CIFS and NFSv3 with authentication tied to openLDAP.
When we change group memberships in LDAP the filer fails to see the change in group memberships for some varying amount of time.
We had been able to use the flush command to force the filer to update it's user/group membership lists. This was changed in our current version, 9.8P1, and we have switched to using the replacement command.
This used to work: set diag; diag nblade credentials flush -node $NODE -vserver $VSERVER -unix-user-name $USER
We think this should be the new command but does not seem to perform as expected: set -privilege advanced -confirmations off; credentials flush -node $NODE -vserver $VSERVER -unix-user-name $USER
The new flush command does not seem to perform with any reliability. It's worth noting that we have many groups so have set the group limit to 512 as described here: https://library.netapp.com/ecmdocs/ECMP1610208/html/GUID-1D3D018C-DF37-4C87-...
As of this writing, we have 2 users whose group memberships were updated over 24 hours ago and they are still unable to access the relevant files over CIFS. We were able to demonstrate that the user can in fact access those files over NFS using the `newgrp` command to select the new group and access the files however after dropping the `newgrp` identity, we were once again denied access to the location.
Are we missing something?
Grateful for any help...
