Cause
Users use their user name and password to log in to the default domain. For all other domains, users
must include the domain name (user@domain or DOMAIN\user).
If you are using the vCenter Server Appliance, other problems might exist.
Solution
For all vCenter Single Sign-On deployments, you can change the default identity source. After that
change, users can log in to the default identity source with user name and password only.
To configure your Integrated Windows Authentication identity source with a child domain within your
Active Directory forest, see VMware Knowledge Base article 2070433. By default, Integrated Windows
Authentication uses the root domain of your Active Directory forest.
If you are using the vCenter Server Appliance, and changing the default identity source does not resolve
the issue, perform the following additional troubleshooting steps.
1 Synchronize the clocks between the vCenter Server Appliance and the Active Directory domain
controllers.
2 Verify that each domain controller has a pointer record (PTR) in the Active Directory domain DNS
service.
Verify that the PTR record information for the domain controller matches the DNS name of the
controller. When using the vCenter Server Appliance, run the following commands to perform the
task:
a To list the domain controllers, run the following command:
# dig SRV _ldap._tcp.my-ad.com
The relevant addresses are in the answer section, as in the following example:
;; ANSWER SECTION:
_ldap._tcp.my-ad.com. (...) my-controller.my-ad.com
...
b For each domain controller, verify forward and reverse resolution by running the following
command:
# dig my-controller.my-ad.com
