By default weblogic has a embedded LDAP server within . which is listening on the admin server's listen port.
for example if your WL ADMIN server is running on <hostXXX: 7004 > . then its embedded ldap server is available on
ldap://hostXXX:7004
but if you enable the SSL port of the admin server (ex : 7008 ) then its available to ldaps//hostXXX:7008 as well.
but for your query : where can i check that ,my application is using ldap or ldaps?
if you have configure any external authentication provider with ldaps then your app is using ldaps . otherwise if it connects to the LDAP server through ldap then it uses ldap.
