1. On TDV Server, open ldap.properties file from [TDV Installation Directory]\conf\server\ and take a note of the user search context.
2. Look up the specific user's membership using a third party LDAP tool such as LDAP Browser or LDAP Administrator
3. Update the [domain].all.users.search.context and [domain].user.search.context - Leave out the DC information if it is already part of the defined LDAP URL. Add atleast one of the CN and OU with a pipe symbol as shown below and re-try the login to TDV Studio.
