The fmkomstemp call requires a suffix of XXXXXX for correct operation. Do so in TCB case as well. Note: If something fails and the file resides in this directory, it could be interpreted as a username. Use the ',' character as an illegal character to prevent shadow tools from erroneously accessing this file and assuming that the user actually exists.

shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
