vCenter Server Login Fails Because the User Account Is Locked

When you log in to vCenter Server from the vSphere Client or vSphere Web Client login page, an error indicates that the account is locked.

Problem

After several failed attempts, you cannot log in to the vSphere Client or vSphere Web Client using vCenter Single Sign-On. You see the message that your account is locked.

Cause

You exceeded the maximum number of failed login attempts.

Solution

• If you attempted log in as a user from the system domain (vsphere.local by default), ask your vCenter Single Sign-On administrator to unlock your account. If the lock is set to expire in the lockout policy, you can wait until your account is unlocked. vCenter Single Sign-On administrators can use CLI commands to unlock your account.
• If you log in as a user from an Active Directory or LDAP domain, ask your Active Directory or LDAP administrator to unlock your account.
