Dell OpenManage VMware "Login failed....Authentication failure."

We were able to get OpenManage installed and running via this original post  ( and were able to login initially but now get an error "Login failed....Authentication failure. For more information, see online help." when trying to login to Dell OpenManage.  I'm using the same credentials and IP address to connect, we haven't changed the IP or credentials for root.   I haven't tried rebooting the VMware server yet, but did reinstall openmanage client on the windows 7 machine it's on to no avail.  The firewall is turned off on the Win 7 machine.  What could be going on here?

Reading through that set of posts, this looks like a known problem with ESXi.

I suggest adding the script they mention and set it up as a scheduled task in Windows. set it to run once or twice a day as needed ahead of the time when you normally expect to need access to OSMA.

There are a few versions based on the version of ESXI you are running:

1. Running the bellow commands via ssh works for me. I have this same issue.
(only restarts OMSA and wsman. Does not affect VMs or ESXi services)

# /usr/lib/ext/dell/srvadmin/bin/dataeng restart
# /etc/init.d/wsman restart

/bin/kill $(cat /var/run/
/bin/echo '15   0,12 *   *   *   /etc/init.d/wsman restart' >> /var/spool/cron/crontabs/root
/usr/lib/vmware/busybox/bin/busybox crond

I've had the same problem. I moved from IE to Firefox and it worked. You might try Chrome also.

If you get a warning, just select Continue Anyway.

Thanks for the suggestion, firefox has the same result, chrome gives an error that the browser isn't supported.  

I was able to login after running this command:
The current workaround is to issue “/etc/init.d/wsman restart” on the ESXi host shell.

How to get around having to do this though...?

And it takes about 30 sedonds for a page to come up in open manage once selected.  Any thoughts on how slow it is?

Ok great!  I know how to set scheduled tasks to run but I'm not sure of how to pass this restart OMSA command other than via WinSCP utility I've been using to connect to the VMware server.  If I want use windows scheduled tasks what method would I use to pass that restart command?

This was the solution and we ended up just making notes on how to do the reset via winscp instead of created a scheduled task to keep Openmanage accessible all the time.
