What is Active Directory and how to login to eMAM when ‘Active Directory Login’ option is enabled?

Active Directory (AD) is a directory service created by Microsoft for Windows Server operating systems which allows storing all the user accounts and passwords in one protected location, improving database security.
 If eMAM is implemented in an Active Directory/LDAP environment, then this person will also need to have knowledge and permission to create LDAP/AD users.  Each AD user requires a unique login username and password to access the eMAM system. Organizations can use LDAP/Active Directory to maintain users by roles.

If ‘Active Directory Login’ option is enabled, user must login using ‘Domain Username’ and ‘Domain Password’, which is validated against LDAP. If validation is successful, eMAM system allows user to login to the application.  This authentication can be done at organization level, or at the unit level. Users belonging to one business unit can log into their unit only, and not to the other units. 
 For Active Directory login, user needs to contact System Administrator to retrieve the password.
