The correct answer is A. Users are typing the password incorrectly. B. Users are in a forest that has 1-way trust. Login failures with 'Incorrect Username/Password' on a PSC configured with Active Directory LDAP can result from wrong credentials or Active Directory trust relationship issues.

Question

When attempting to log in with the vSphere Web Client, users have reported the error:

Incorrect Username/Password The administrator has configured the Platform Services Controller Identity Source as:

  • Type. Active Directory as an LDAP Server
  • Domain: vmware.com
  • Alias: VMWARE
  • Default Domain: Yes

Which two statements would explain why users cannot login to the vSphere Web Client? (Choose two.)

Options

  • AUsers are typing the password incorrectly.
  • BUsers are in a forest that has 1-way trust.
  • CUsers are in a forest that has 2-way trust.
  • DUsers are logging into vCenter Server with incorrect permissions.

Why each option

Login failures with 'Incorrect Username/Password' on a PSC configured with Active Directory LDAP can result from wrong credentials or Active Directory trust relationship issues.

AUsers are typing the password incorrectly.Correct

Users typing the password incorrectly is a direct cause of the 'Incorrect Username/Password' error regardless of identity source configuration.

BUsers are in a forest that has 1-way trust.Correct

A one-way trust means vCenter's domain can authenticate users from the trusted domain, but users in a forest with a one-way trust where the vCenter domain is not trusted cannot authenticate, causing login failures.

CUsers are in a forest that has 2-way trust.

A two-way trust allows mutual authentication between forests, so users in a two-way trusted forest would be able to authenticate successfully without this error.

DUsers are logging into vCenter Server with incorrect permissions.

Incorrect permissions would result in an authorization error after successful authentication, not an 'Incorrect Username/Password' error at login.
