I'll convert sysinstall to use shortly) and a simple call which uses
this mechanism to implement an /etc/auth.conf file. I'll let Mark Murray
handle the format and checkin of the sample auth.conf file.

bumped only 0.1 or 1.0 between releases. (See handbook.)
Note that if you have built world in -current in the last 48 hours or
so, you should manually remove /usr/lib/libutil.so.2.3 before
rebuilding world to cleanse your system.
o Incorporated BSDI code and enhancements, better logging for error
checking (which has been shown to be a problem, and is therefore
justified, imho); also some minor things we were missing, including
better quad_t math, which checks for under/overflows.
o setusercontext() now allows user resource limit overrides, but
does this AFTER dropping root privs, to restrict the user to
droping hard limits and set soft limits within the kernel's
allowed user limits.
o umask() only set once, and only if requested.
o add _secure_path(), and use in login.conf to guard against
symlinks etc. and non-root owned or non-user owned files being
used. Derived from BSDI contributed code.
o revamped authentication code to BSDI's latest api, which
includes deleting authenticate() and adding auth_check()
and a few other functions. This is still marked as depecated
in BSDI, but is included for completeness. No other source
in the tree uses this anyway, so it is now bracketed with
#ifdef LOGIN_CAP_AUTH which is by default not defined. Only
auth_checknologin() and auth_cat() are actually used in
module login_auth.c.
o AUTH_NONE definition removed (collided with other includes
in the tree). [bde]
o BSDI's login_getclass() now accepts a char *classname
parameter rather than struct passwd *pwd. We now do likewise,
but added login_getpwclass() for (sort of) backwards
compatiblity, namely because we handle root as a special
case for the default class. This will require quite a few
changes elsewhere in the source tree.
o We no longer pretend to support rlim_t as a long type.
o Revised code formatting to be more bsd-ish style.
were added with the login class stuff. This is needed since libutil.so.2.1
is what is used in RELENG_2_2 and well into the release cycle. We only
bump once per release cycle as needed.
also add the missing declaration of forkpty() to libutil.h.
Btw., the calling interface for login(3) is crude. Some better
abstraction is needed, perhaps similar to logwtmp(3).
2.2 candidate, but i'll wait for the spelling police first. :)
Install (optional) libutil.h with prototypes for the functions and
document this in the man page.
minor cleanups to the various routines, include the prototype file, declare
return codes etc.
replace the dozen other various hacks in the code that do all sorts
of crude things including spamming the envrionment strings with the new
argv string.
This version is mainly inspired by the sendmail version, with a couple of
ideas taken from the NetBSD implementation as well.
