For Trusted Mode: Use the SAM/SMH interface or edit the /tcb/files/auth/system/default file and update the u_maxtries attribute. See the below example: :u_maxtries#3: If manually editing the file, save any change(s) before exiting the editor. For SMSE: Note: There may be additional package/bundle updates that must be installed to support attributes in the /etc/default/security file. Use the SAM/SMH interface (/etc/default/security file) and/or the userdbset command (/var/adm/userdb/* files) to update the attribute. See the below example: AUTH_MAXTRIES=2 Note: Never use a text editor to modify any /var/adm/userdb database file. The database contains checksums and other binary data, and editors (vi included) do not follow the file locking conventions that are used to control access to the database. If manually editing the /etc/default/security file, save any change(s) before exiting the editor.
