>Environment:
SunOS cs 5.5.1 Generic_103640-06 sun4u sparc SUNW,Ultra-1
gcc version 2.7.2
>Description:
I have a situation where it is convenient to use the NIS passwd.byname DBM as
the AuthDBMUserFIle.  As the first field in the data returned from the DBM is
the username, this needed to be stripped, and the password extracted from the
2nd field.  A patch is included below.
