Apex LDAP authentication - Post-Authentication Procedure

Hi All,

Application Express 19.2.0.00.18.

For my application, I created a custom authentication scheme based on the existing "LDAP Directory" scheme type. I am able to log into the application after authentication, but I need to find which LDAP groups the "logged in" user is a member of. I know that APEX_LDAP package functions MEMBER_OF or MEMBER_OF2 can be used to get this from the LDAP server, but both functions require both username and password again, but I am not sure if I have access to the password after login to use it in these functions. Do I have to write my own custom authentication
