I have integrated Active Directory and assign the permission to AD users but still i am unable to login with AD users in vSphere web client
I had same issues, try with option 'Active Directory as an LDAP server'

Not working
on the configuration page ,'Test Connection' results are successful ? Also check if you are adding AD group for authentication as these are not supported. Add individual AD user or create SSO group to add AD users.
1. Test Connection was completed successfully.
2. We are using individual AD user not user group for the permission assignment
3. User has global permission assigned.
What is the exact error your'e seeing, invalid credentail/not recognized or permissions etc ?
Just "Authentication Error"
