The issue documented here is limited to the version 10g or higher listener or lsnrctl utility.


When using a 10g listener or higher, it is possible that the error TNS-1189 "The listener could not authenticate the user" may occur intermittently (or very frequently) while performing listener operations from within the same LSNRCTL session.  For example:

LSNRCTL> set trc_level 16

LSNRCTL> save_config



The listener.ora file may have been edited recently or this is a new installation.
