Hi,
Fine , Try this
1) Create a security group in your Active Directory named “ESX Admins.” You must use this exact name or the process doesn’t work. Once created populate this group with the users you wish to have the capability to manage your ESX hosts.
2) Open your VMware VI Client. Before joining your servers to the domain first we need to verify that DNS and NTP are both configured properly, pointing both back to the sources for your Windows Active Directory infrastructure.
3) Now in the left menu, click the host you want to add to AD, and then click on the configuration tab. Once in configuration, choose “Authentication Services” from the Software submenu. Once there first notice that the current Directory Services type is Local Authentication, meaning it is using the local user groups.
4) Join the host to the domain, you need to click the Properties link in the top right corner, launching the Directory Services Configuration dialog. At this point it should feel much like joining a workstation to the domain. Set the Directory Service type to Active Directory and supply your domain name, making sure you use the FQDN rather than the NetBIOS version. Now when you click “Join Domain”, you will be prompted for Active Directory credentials capable of writing to AD. Finally, click Join Domain again.
5) Once the above step completed, the VI Client will report that it is joined to the domain and authenticating to the domain. Looking further in to the Active Directory of Users and Computers, the host will be shown with a computer account in the directory.
6)Now the users who access Virtual Machines can now use your centrally managed Active Directory credentials to authenticate to ESX or ESXi.
