Recently reported some issues involving /etc/login.defs util-linux, pam
and shadow-utils. See bz#1884702 and bz#1884695
While doing an unrelated test on the test environment of the above issue,
I just noticed the @summary message when adding a test user with 'useradd',
and using LOGIN_PLAIN_PROMPT in /etc/login.defs.
Feel free to reassign to shadow-utils if that is the case.
This is necessary to fix in shadow-util. It seems RHEL-8 has already a patch for this issue.
Note that we're trying to fix it also in upstream level and there is a shadow-utils pull-request to add all missing options.
For more details see: https://github.com/shadow-maint/shadow/issues/276
Is this an actual error message or just a warning? I mean, where you able to add the user?
It is just a warning message. User can be added normally.
Since this is a cosmetic issue for RHEL7 and it has already been fixed in RHEL8 I'm closing it as won't fix.
