Could anyone please provide the detailed level understanding of creating users through Generic LDAP in User Directory Connectors on QMC and Could it be used to sync the Database users for Qliksense login authentication?
It is perhaps more specific to Active Directory, but I believe many details are similar/same.
To answer your question, yes, the users from LDAP will be able to log into Qlik, once you sync them to Qlik.
You need to also give them tokens in Qlik, and also grant them permission to streams, etc. via security rules. (You can theoretically achieve both of these steps by setting up rules that use attributes from your LDAP data. Or you do it manually for each user in Qlik.)
