Authenticate via LDAP - 2 diffrent "LDAP DN Strings"

Question

Hello!
My Application gives access to users via LDAP.
I want to give access to users located in 2 diffrent LDAP - Objects.
Can anyone help me to solve the problem?

Answer 1

My idea was to create a function that calls 2 times function authenticate (http://www.oracle.com/technology/products/database/application_express/howtos/how_to_ldap_authenticate.html)
like this:
create or replace function "AUTHENTICATE_AD"
(p_uname in VARCHAR2, p_password in VARCHAR2)
return BOOLEAN
is
begin
RETURN(authenticate(LDAP_DN_STRING1, P_PASSWORD,LDAP HOST,LDAP PORT))
OR
(authenticate(LDAP_DN_STRING1, P_PASSWORD,LDAP HOST,LDAP PORT))
end;
Help of Fiel "Authentication Function" says:
"[...]The Application Express engine expects this function to have the signature (p_username in varchar2, p_password in varchar2) return boolean. The value of the username and password fields passed to the login API, which is called by the login page, will be passed to your function. [...]
When I insert AUTHENTICATE_AD into "Authentication Function" and try to logon an error message diplayed :
ORA-06550: Zeile 2, Spalte 1: PLS-00306: Falsche Anzahl oder Typen von Argumenten in Aufruf von 'AUTHENTICATE_AD' ORA-06550: Zeile 2, Spalte 1: PL/SQL: Statement ignored
I don't know which arguments are given!
