No authentication asked in vCenter 6.7 - A server error occurred. [500] SSO error: null


I upgraded my vCenter Appliance from 6.5 to 6.7d version. Everything was working except my Replication appliance. I registred again my Replication Appliance and received a lot of errors from the vCenter. I restarted my vCenter and have these messages (no more credential asked):

Flex Web client:

A server error occurred.

[500] SSO error: null

Check the vSphere Web Client server logs for details.

HTML5 Client:

[400] Une erreur s'est produite lors de l'envoi d'une demande d'authentification vers le serveur vCenter Single Sign-On - Une erreur s'est produite lors du traitement des métadonnées pendant la configuration de vCenter Single Sign-On - null.

I made a lot of investigations and times are ok on my both ESXi and vCenter.  I found these errors in the virgo file:

I found too I have no more vsphere-webclient user as it should be (copy paste from a website with another GUID than mine)




vsphere-webclient-bf048b3a-231e-40b0-96ea-e5792f7fa65b => this one is missing for me.

I have well the three first accounts but not the last one. I think it is not normal... . Can I add it manually (grep with my GUID)? Or do you have another solution please?

Thank in advance if you can help me!

How did you confirm that the webclient solution user is missing as the webclient is not accessible?

Kindly contact the support  if the webclient solution user is missing if true.

Thanks for your answer, through the ssh command:

/usr/lib/vmware-vmafd/bin/dir-cli service list

In fact more and more I think it happened when I put the ESXi containing the Vcenter VM in a cluster.

Very rarely I have seen this scenario of missing solution user in 6.x versions. I would suggest to open a Support ticket if you have active support entitlement.

Ok, thanks for your answer. I chose to recreate a new vCenter because I lost already too much time.

Best regards,
