ORA-0036: maximum number of recursive SQL Levels 50 - when processing SSO post login procedure

xarg-XrcJun 18 2013 — edited Jun 19 2013

Not sure if I have hit a bug:

I am implementing SSO (via OAM) to application in Apex 4.2.2 running on Apex Listener 2.0 in Weblogic 10g.

I am using http header variable:

HTTP Header Variable Name: OAM_REMOTE_USER

URL: #CALLBACK#

Verify Username: Each Request

My Post Authentication Procedure Name : utils.sso_sentry

The code is

procedure sso_sentry
    IS
        n_hostname VARCHAR2(400):=NULL;
        n_oam_remote_user VARCHAR2(1000):= NULL;
        n_session_id    NUMBER := NULL;
        n_protocol VARCHAR2(1000):= NULL;
    BEGIN
        n_hostname:= OWA_UTIL.get_cgi_env('HOSTNAME');
        n_oam_remote_user := OWA_UTIL.get_cgi_env('OAM_REMOTE_USER');   
        n_protocol := owa_util.get_cgi_env('REQUEST_PROTOCOL');
       
       
        insert into test_table(item,value) values('oam_remote_user', n_oam_remote_user);
        COMMIT;

        APEX_CUSTOM_AUTH.SET_USER(n_oam_remote_user);
        apex_authentication.send_login_username_cookie(p_username => lower(n_oam_remote_user));
       
        n_session_id := APEX_CUSTOM_AUTH.GET_SESSION_ID_FROM_COOKIE;


       
         INSERT INTO test_table(item,VALUE) VALUES('REQUEST_PROTOCOL', n_protocol);
        COMMIT;
       
        APEX_CUSTOM_AUTH.POST_LOGIN(
            p_uname             => n_oam_remote_user,
            p_session_id        => n_session_id,
            p_app_page          => '100:1');

          OWA_UTIL.redirect_url('/apex/f?p=' || '100' || ':' || '1' || ':'||n_session_id||':');
    end sso_sentry;

When run the application, I am going into the SSO page where I enter my username & password. Then after clicking login, I am redirected to page:

https://<myhostname>/apex/apex_authentication.callback?p_session_id=2035365908499&p_app_id=100&p_ajax_identifier=85C8EB491758A895E4A24EC9E2A58538E8C944B10C482A00A8501D58A3285C86

With the error message:

Error in PLSQL code raised during plug-in processing.

ORA-00036: maximum number of recursive SQL levels (50) exceeded

I am not sure why its recusrively running my post login procedure in a infinite recursive loop. Is this a bug or should I be doing anything different? Any help appreciated. Cheers.

Environment:
Apex 4.2.2 with OAM single sign on

Apex Listener 2.0
