Explanation
The Single Sign On (SSO) login to the vSphere Server failed. Possible
reasons for this failure include the following situations:
- A time difference exists between the vSphere Server clock and
the client clock that exceeds 10 minutes.
- The SSO server accesses a non-default port. This issue can occur
when the SSO server is installed on the same system as the VMware
vCenter.
System action
The system attempts a credential login as a result of the SSO login
failure.
User response
