You can configure some of the ways vCenter Server interacts with the user directory server that is configured as identity source. For details about identity sources, see vSphere Security.
- In the vSphere Web Client, navigate to the vCenter Server instance.
- Select the Manage tab.
- Under Settings, select General.
- Click Edit.
- Select User directory.
- In User directory timeout, type the timeout interval in seconds for connecting to the user directory server.
- In Query Limit, type the number of users and groups for which you can associate permissions on the child inventory objects of the vCenter Server system.
You can associate permissions with users and groups from the Add Permissions dialog box that displays when you click Add permissions in for a vSphere inventory object.
- Select the Enabled check box next to Validation to have vCenter Server periodically check its known users and groups against the user directory server.
- In Validation Period, enter the number of minutes between instances of synchronization.
- Click OK.
