Can't get past Update manager certificate warning

[pdrace]

I have an issue with Update manager certificates warnings when connecting to a Vcenter server.

The standard security warnng regarding an untrusted certificate comes up but I can't access the ignore button or check the box to install the certificate. I have to use task manager to kill it. This doesn't happen on all machines. If I log in directly in to the server I can open the client according to who I log into the server as. I tried deleting the profiles of the users I had issues with but that made no difference .

maybe restart the VUM and vCenter Services and try again?

Restarted services, same result.

this sounds to me like an issue with the plugin. Have you tried to uninstall the plugin (VMware vCenter Update Manager Client) from the machine in which your launching the vSphere4 Client from? Once complete, download and install the VUM plugin again?

I uninstalled the plug in and then logged in with one of the ids that has a problem and reinstalled it. It now works with that ID but still has the problem if I log in with other IDs. It appears there is some kind of issue with the certificate on a per user basis rahter than the plug in.

I am experiencing the same is in vSphere 4.0.0 after adding an Update Manger server to our environment.  The issue is apparent on any server on which the vSphere client is installed.  Did you find a solution?  What I am see is this:

1. User 1 logs into the vSphere client on Server 1 and installs the UM plugin.  That user can access vSphere without issue and everything seems to work fine.

2. User 2 logs into the vSphere client on Server 1 and gets the certificate warning.  vSphere freezes and the process has to be killed.

3. User 1 logs onto Server 1 and uninstalls the plugin.

4. User 2 logs onto Server 1, loads vSphere without issue and installs the plugin.

5. User 1 and 2 can now login to vSphere successfully on Server 1.  However, users 3,4,5 get the certificate issue.

Basically, if every user logs on, installs the plug and then removes it, with the last user leaving the plugin installed, there isn't an issue.  However, this really isn't a practical solution in our environment as we have a number of administrators and a number of servers on which the vSphere client is installed.  Another thing I have noticed is that if user 1 installs the plugin, if user 2 checks Add/Remove programs the plugin is not shown.  However, if user 1 checks Add/Remove programs the plugin is listed.

This was happening to myself as well. In my case this was due to setting up the message of the day. I'm no programmer but i have a feeling the motd is hidden in the background somewhere taking focus and the user is simply unable to see it. Therefore the user gets "stuck" at the certificate warning for the update manager. I figured this may be addressed in later versions but it appears to still happen in vSphere client 5.0 623373 (win2k8 R2).

Ignitor, you are spot on.  Disabling MOTD has made the issue go away for me as well.  We actually halted the deployment of Update Manager to our Live system because of this.  To be honest, we already manage all the guests with ADS/SMS/SCCM so it was just for host remediation.  Still, it's good that we've now got it working and there's another solution for anyone coming across this issue.

That's great to hear!  Now we just need VMWare to fix it.
