nsrexecd: Failed to authenticate

Question

I'm backing up an xp client with St Bernard's Open File Manager installed. I get the error:

nsrexecd: Failed to authenticate user with GSS Legato authentication User: SYSTEM, domain: NT Authority

nsrexecd service is running as system on the client and the Open File Manager is running as domain administrator. Backups still work but this error appears about 7-8 times with one backup.

Any help would be appreciated! Karen

This problem is not related to OFM, but rather to NW. This is due to newly introduced auth model. You can ignore this message as so far from what I have seen it's just harmless. You may wish to open a case with support to confirm it.

The problem does appear to be down to Legato Networker authentication however the other XP networker clients don't generate the error.

We ran:
nsradmin -p nsrexec -s clientname
print type:NSRLA
update auth methods: "0.0.0.0/0,oldauth/nsrauth"

Reversing the order makes no difference and unfortunately since the change, which I have rolled back I can no longer back up the client. Any ideas? Thanks

Reinstall the client in following manner:- uninstall existing version- delete nsr directory- install it againThat should start backups again.

Do you mean the open file manager or networker client??Thanks

Could you clarify the facts here - you state initially "Backups still work but this error appears about 7-8 times with one backup" but your last post states that backups have not been successful since the upgrade.

I would suggest restarting the client service first of all and see if that still gives issues; if that does not work follow Hrvoje's suggestion to reinstall the client software. If that does not work there is a process on p568 for exporting the authentication credentials which might work; however you are using both old and new authentication so it should work even if nsrauth is failing.

The other thing that concerns me is that your nsrla.res has the line:

auth methods: "0.0.0.0/0,oldauth/nsrauth"

My nsrla.res and the one in the manual have oldauth and nsrauth the other way round - not too sure whether it will work like this (which says use the weaker old authorization first but if that fails use the stronger nsr authentication - it would be interesting to see if you have a failure for oldauth prior to the failure for nsrauth).

Do you mean the open file manager or networker client?? Backup client - OFM is not related.

Hi Thanks for the help!To clarify:I had successful backups with OFM including open files but got a GSS errorThe order of auth was changed, backups failed.If I stop OFM service backups work, don't get a GSS error but no open files backed up.Haven't reinstalled networker client but will suggest to EMC support.The help is appreciated!Karen

If I stop OFM service backups work, don't get a GSS error but no open files backed up.

Interesting - I didn't expect this at all (GSS vs OFM). Thanls for sharing this. Keep us updated with what happens.

Still waiting on EMC support to come back to me on this.

Finally got a solution. We had to stop the Symantec Anti-Virus update definitions service. There is a problem with the client v. 10.0 and the memory access that conflicts with OFM. I stopped the service and OFM worked fine. We're upgrading to the latets version of Symantec Anti-virus which is said to resolev this issue.

Thanks for the help!
