Using DBMS_LDAP in Apex

Question

Hi there
I have the following problem. I have a simple function which uses DBMS_LDAP package. For testing purposes, when I call the function from sql*plus or sqldeveloper, it works fine and I can authenticate the user in AD. However, when using the same function call in Apex, the screen 'freezes' for about a minute and returns 'IE cannot display page' message. It looks like getting time out. Is this a network/firewall issue? Is Apex using some kind of proxy and cannot establiss LDAP session? Your help is really appresiated much.
thanks, Ed

thank you for clarification. Really appreciate your help. I was able to get the list. Here is the procedure. The line that fails is highlighed. Basically it can't initialize the session on AD server...
declare
     p_username          varchar2(25):='test';
     p_password          varchar2(25):='test';
     l_user               varchar2(256);
     l_ldap_server     varchar2(256)     := 'AD host';
     l_domain          varchar2(256)     := 'domain';
     l_ldap_port          number               := 389;
     l_retval          pls_integer;
     l_session          dbms_ldap.session;
     l_cnt               number;
begin
--     l_retval := dbms_ldap.unbind_s( l_session );
     l_user               := p_username||'@'||l_domain;
*     l_session          := dbms_ldap.init( l_ldap_server, l_ldap_port ); -- start session*     
l_retval          := dbms_ldap.simple_bind_s( l_session, l_user, p_password ); -- auth as user
     l_retval          := dbms_ldap.unbind_s( l_session ); -- unbind
     dbms_output.put_line( 'yes');
exception when others then
dbms_output.put_line( 'no');
raise_application_error(-20101, 'invalid user');
     end;
thanks, Ed
