I have two unix server ( eg. they are Server A , Server B ) and want to use LDAP to control the user profile , each of these servers have some database and application are running , assume I have setup Server A as LDAP server . Now I am not too understand the practice of it, could anyone can advise .

1. If the password is centralized at Server A that means all users will login to the Server A first , could advise how the user can use the application at Server B ? should I setup ssh for the user who want to use Server B ?

2. How the path is shared between the servers ?

thx in advise.

The applications on server B have to know how to use the LDAP service. When a user wants to use an application on server B, they will log on to that application. Then the application will use the credentials that the user typed to ask the LDAP server if it's ok. The user shouldn't have to know about the LDAP, the application needs to do it for them.
