Description of problem:
SELinux is preventing /usr/sbin/useradd from 'write' accesses on the file /etc/passwd-.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/etc/passwd- default label should be passwd_file_t.
Then you can run restorecon.
# /sbin/restorecon -v /etc/passwd-

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that useradd should be allowed write access on the passwd- file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep useradd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
