wwsso_auth_external , in the file ssoxnete.pkb . This file can be found in the
directory $ORACLE_HOME/portal30/admin/plsql/sso . The only two functions
that must be modified here are authenticate_user and
get_Authentication_Name . The modified functions are documented below
with the changes highlighted in bold.

debug_print(’Identity ID : ’ || l_http_header);
l_ssouser := l_http_header;
IF ( (l_ssouser IS NULL) or
( INSTR(l_ssouser, GLOBAL_SEPARATOR) != 0) ) THEN
debug_print(’malformed user id: ’
|| l_ssouser
|| ’ returned by wwsso_auth_external.authenticate_user’);
RAISE EXT_AUTH_FAILURE_EXCEPTION;

p_user := NLS_UPPER(l_ssouser);
return 0;
