            Bug ID: 227541
           Summary: 'pw userdel' probrem with NIS Master
           Product: Base System
           Version: 11.1-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: bin

          Reporter: hsakamt at tsnr.com

Hello,

I setup a FreeBSD box as NIS master. The 'useradd' and 'usermod' options of the
'pw' command work fine, but there are two problems with the 'userdel' option.

1. 'pw userdel' always fail with error:
pw: pw_copy(): No such file or directory

Because "GETPWNAM(user)" at line 102 of pwdupd.c seems to have destroyed the
'pwd' global variable. 

2. 'pw userdel' does not update "NIS maps" with '-Y' option.


Workaround patch for 11-STABLE:

 }

Thank you.
