ADNR uses the z/OS® UNIX dig command to perform zone transfers from managed zones. The z/OS UNIX .digrc file can provide defaults for each user for the dig command. This file is read and used if it appears in the user's home directory. Because this file can cause ADNR to function incorrectly, ADNR fails initialization if this file is found in ADNR's working directory. However, ADNR does not search for this file after initialization. ADNR's working directory is specified when ADNR is defined to the security server (RACF®).
