Login failed due to invalid credentials for one or more vCenter Server systems

[ZeUS32]

I am able to login using AD credentials on both production and DR.

From production vcenter I can see both vcenter servers fine. But when I log into the DR vcenter I get:

Login failed due to invalid credentials for one or more vCenter Server systems

Also, when I click on the Prodcution vcenter from the DR webpshere I get an error message saying:

You have no priveledges to view this object or it does not exist.

Periodically, when logged into the websphere from DR I would receive a
pop error:

[admin]

what is version of the vcenter server and what you see in vpxd.log files ?

[ZeUS32]

vCenter 5.5

where are these log files located?

[admin]

-login using web client by administor@vsphere.local and make Identity source as default.

[ZeUS32]

Active Directory is set as Default. The server URL is empty. Is this supposed to be populated?

[admin]

It should show the domain name.

[ZeUS32]

the domain is actually populated with the correct domain name.
