When you issue the LISTUSER command for a protected user, the PROTECTED attribute is listed and the user's password interval is listed as N/A. (These values reflect that a protected user need not supply a password or password phrase to enter the system.)

Protected users are identified in IRRDBU00 output by the PRO value in the USBD_NOPWD field of the user basic data (record type 200). However, the PASSINT field for the protected user might contain a password interval value, such as 060. Ignore the contents of the PASSINT field for protected users.
