If you have an existing LDAP/MSAD user directory, use a standard LDAP browser to explore the user directories that store user credentials before provisioning EPM System applications. The settings that the LDAP browser uses to connect to the user directory are identical to those that EPM System applications use to connect to the user directories. You can download a free LDAP browser.
Use the browser to check these points:
Whether you can connect to the user directory from the server that you are using
The response time
The starting point (base DN) for any search of the user directory
A count of the users and groups under the starting point
To ensure acceptable login performance:
Minimize the number of groups and users for EPM System applications.
Ensure that the server machines that host EPM System applications are in the same geographical location as the server machines that host the user directories used in the provisioning process.
Find an optimal starting point for searches or create a custom group hierarchy.
For the first item in the search order, specify the directory from which the greatest number of users log in.
