Authentication failing for APEX against OID when uppercase used in password

Question

We are using Application Express 3.1. I am authenticating against OID 10.1.2.2 and noticed some users were having problems
logging into APEX. They are getting "Invalid Login Credentials". I eventually workout it was when they were authenticating using a password
having a uppercase character ... "Blackhawk" is one example. We authenticate discoverer using OID and do not have the same problem.
Has anyone else encounter this problem please ?
Cheers Rod
The Function I use is shown below:
DECLARE
V_TEST BOOLEAN;
V_EXIST NUMBER ;
BEGIN
SELECT COUNT(*) INTO V_EXIST FROM BE_MANAGERS
WHERE MANAGER_CSO_CODE = :APP_USER
AND FINANCIAL_YEAR_ID = BE_BUDGETS_APEX_PKG.CURRENT_FINANCIAL_YEAR ;
IF V_EXIST = 0 THEN
HTMLDB_APPLICATION.G_UNRECOVERABLE_ERROR := TRUE;
OWA_UTIL.REDIRECT_URL('f?p=' || v('APP_ID') || ':101:' || v('APP_SESSION') );
END IF ;
V_TEST := HTMLDB_LDAP.IS_MEMBER
( p_username => :APP_USER, p_pass => NULL
, p_auth_base => 'cn=Users,dc=planforlife'
, p_host => 'oraapp01'
, p_port => '389'
, p_group => 'OID-PilotUsers'
, p_group_base => 'cn=vaultgroups,cn=Groups,dc=planforlife');
IF V_TEST = FALSE THEN
HTMLDB_APPLICATION.G_UNRECOVERABLE_ERROR := TRUE;
OWA_UTIL.REDIRECT_URL('f?p=' || v('APP_ID') || ':101:' || v('APP_SESSION') );
END IF;
EXCEPTION
WHEN OTHERS THEN
HTMLDB_APPLICATION.G_UNRECOVERABLE_ERROR := TRUE;
OWA_UTIL.REDIRECT_URL('f?p=' || v('APP_ID') || ':101:' || v('APP_SESSION') );
END;

Rod:
Are you sure it is not the 'username' which is causing the issue ? If it is the username then to preserve the case in which the username is entered you will need to set the ' p_preserve_case' parameter to true in the call to APEX_CUSTOM_AUTH.LOGIN . This API is invoked in the application's login page as an after-submit page process.
