Users can log in to vCenter Server only if they are in a domain that has been added as a vCenter Single Sign-On identity source. vCenter Single Sign-On administrator users can add identity sources from the vSphere Web Client.
About this task
An identity source can be a native Active Directory (Integrated Windows Authentication) domain or an OpenLDAP directory service. For backward compatibility, Active Directory as an LDAP Server is also available.
Immediately after installation, the following default identity sources and users are available:
- Log in to the vSphere Web Client as firstname.lastname@example.org or as another user with vCenter Single Sign-On administrator privileges.
Users with vCenter Single Sign-On administrator privileges are in the CAAdmins group.
- Browse to .
- On the Identity Sources tab, click the Add Identity Source icon.
- Select the type of identity source and enter the identity source settings.
Active Directory (Integrated Windows Authentication)
Use this option for native Active Directory implementations. The machine on which the vCenter Single Sign-On service is running must be in an Active Directory domain if you want to use this option.
Active Directory as an LDAP Server
This option is available for backward compatibility. It requires that you specify the domain controller and other information. See Active Directory LDAP Server and OpenLDAP Server Identity Source Settings.
Use this option for an OpenLDAP identity source. See Active Directory LDAP Server and OpenLDAP Server Identity Source Settings.
Use this option to add the local operating system as an identity source. You are prompted only for the name of the local operating system. If you select this option, all users on the specified machine are visible to vCenter Single Sign-On, even if those users are not part of another domain.Note:
If the user account is locked or disabled, authentications and group and user searches in the Active Directory domain will fail. The user account must have read-only access over the User and Group OU, and must be able to read user and group attributes. This is the default Active Directory domain configuration for user permissions. VMware recommends using a special service user.
- If you configured an Active Directory as an LDAP Server or an OpenLDAP identity source, click Test Connection to ensure that you can connect to the identity source.
- Click OK.
What to do next
When an identity source is added, all users can be authenticated but have the No access permission. A user with vCenter Server Modify.permissions privileges can assign permissions to users or groups of users to enable them to log in to vCenter Server. See Assign Permissions in the vSphere Web Client.
