All calls to odbc_connect() fails after upgrading from PHP 4.2.1 to 4.2.2.  PHP is running under Apache 2.0.39 (not IIS) as sapi.  This occurs with both MS's and Oracle's ODBC drivers.  DSNs set up for this purpose work fine when executed with the MS ODBCTe32.exe tool and MS Access.  The PHP works when directed to non-Oracle DSNs and when transferred to another system set up similarly but using 4.2.1. ODBC traces, Oracle traces, and the php error logs all point to an authentication failure (perhaps related to wide/multibyte string conversion to ANSI ??).

PHP-error.log:
SQL error: [Oracle][ODBC][Ora]ORA-12640: Authentication adapter initialization failed

Oracle sqlnet.log:
