I setup a vSphere 5.5 lab at home. Everything went fine during installation. I chose the custom installation method of vCenter. Post installation I gave administrative delegation to my Domain Admins group in Web Client. I am able to login to web client by user administrator@vsphere.local and I can see server in vCenter inventory list.
But When I login with user administrator@mydomain.com I cannot see any vCenter listed in Inventory. Also I cannot login with any other user who are member of domain admin group except domain administrator.
I also follow the KB 2058796 to configure the primary Active Directory or OpenLDAP identity source as the default domain by following below steps but could not get any luck.
I also tried to re-install the vSphere vCenter 5.5 but getting same issue.....PLS HELP
What about permissions under vcenter?
Permission has also been given to user under administrator roles.
Do you have the same problem accessing from vshpere client? Could you post a snapshot showing permissions under vcenter tab (vcenter -> your-vcenter-name -> manage -> permissions)? Are you using VA or vcenter under Windows 2008-2012? Did you see anything under vcenter logs after successful or unsuccessful login try?
Thanks linotelera for replying.
Here I am attaching the all screenshots or error and configurations.
Looking best answer.

PLEASE RENAME THE FILE WITH .PDF
seems to be ok... try these:
1. Because is set as default domain, try to login without MYDOMAIN prefix
2. Try to login with user@mydomain.com
3. Try to revoce group under sso and set up permission directly from object (you must see your Administrator members under SSO Configuration / Users / Choose MYDOMAIN from dropdown)
Could you post what you see under event log under vcenter OS (if it is VA login as root user and try to post what you see under /var/log/vmware/vpx/vpxd.log)?
