What is LDAP how to use it:
LDAP directory service is based on a client-server model. One or more LDAP servers contain the data making up the LDAP directory tree or LDAP backend database. An LDAP client connects to an LDAP server and asks it a question. The server responds with the answer, or with a pointer to where the client can get more information (typically, another LDAP server).
No matter what LDAP server a client connects to, it sees the same view of the directory; a name presented to one LDAP server references the same entry it would at another LDAP server. This is an important feature of a global directory service, like LDAP.
Configuring LDAP Authentication
You can configure UNItekTIME to authenticate the requester login with the LDAP. This provides you an advantage of not having to remember too many passwords. For this, you should configure LDAP authentication, then any password change that is made in the LDAP will also reflect in UNItekTIME. So the requesters can login using the login name and password of the system.
LDAP Host must be specified exactly the same as Server Name or IP used in LDAP configuration (As shown in above picture) as well as fill LDAP Port with same port used in LDAP configuration and LDAP Base DN should match with Base DN of LDAP configuration. After giving same LDAP username and password, Click update. LDAP Integration is now configured with UNItekTIME Account. LDAP users can also now login with there already assigned usernames and passwords.
