There was a complaint from users that they cannot access data’s which is storing in NetApp CIFS ( NAS). Below error they were getting while accessing the shared folder from NetApp.
We checked the filer and it is up and running. Also we can able to ping to filer from Domain controller and vice versa.
But the below logs were we can see in NetApp console.
Sat Oct 15 05:20:38 GMT : cifs.trace.GSS:error: AUTH: Unable to acquire filer credentials: (0x96c73a25) Filer and domain time differ by more than 5 minutes.
This made me sure that NetApp filer and Active Directory domain controller time is not matching. so we need to go to filer and check the time is exactly correct with AD. Up to 5 minutes is ok to but if it is more than that you need to sync it.
Go to filer view –> Set date and time–> Modify date and time.
After setting the time match with Domain controller we were able to access the CIFS data.
If the clock is not matching then you cannot join the filer in to the domain and cannot setup the CIFS.
