What is LDAP?
“LDAP stands for Lightweight Directory Access Protocol used for accessing and maintaining distributed directory information services over an Internet Protocol network.”

Why is LDAP used?

LDAP is used for accessing a directory which can consist of a set of objects, users, groups, login, passwords, permissions etc. Its practical use is more in terms of authentication and access control mechanism. LDAP also provides add, delete, search, modify operations. LDAP is not considered as a standard relational database.
LDAP stores the attribute based data and they are generally read specific data. The entries in LDAP are maintained in tree like structure Directory Information Tree (DIT).

I have installed the setup.bat file and at last, it shows an error that the server has stopped. You may start it from the Control Panel.bat or click on the button. When I click or access the path it does not perform any action. The screen remains the same. At times it also shows error for the port 4444 exception in Firewall.
