This is the third beta version of sudo version 1.7. I'd love to
hear reports of success (or failure!) in real-world environments.
Also, the support for setting AIX resource limits needs testing as
I don't have access to an AIX system of my own.

Changes from Sudo 1.7b2:
* Fixed a bug in the sudoers option parsing that was causing
some options to be ignored.
* Unified "sudo -l" output that uses the same format for both
file and LDAP sudoers. For a longer listing, the "-ll" flag
can be used or the "-l" flag may be specified multiple times.
* Improvements to the sudoers.ldap man page.
* Resource limits are now set to the default value for the
user the command is being run as on AIX systems.
* If no terminal is available or if the new -A flag is specified,
sudo will use a helper program to read the password if one is
configured. Typically, this is a graphical password prompter
such as ssh-askpass.
* A new Defaults option, "mailfrom" that sets the value of the
"From:" field in the warning/error mail. If unspecified, the
login name of the invoking user is used.
* Sync with Sudo 1.6.9p14
What's new in Sudo 1.7?
* Rewritten parser that converts sudoers into a set of data structures.
This eliminates a number of ordering issues and makes it possible to
apply sudoers Defaults entries before searching for the command.
It also adds support for per-command Defaults specifications.
* Sudoers now supports a #include facility to allow the inclusion of other
sudoers-format files.
* Sudo's -l (list) flag has been enhanced:
o applicable Defaults options are now listed
o a command argument can be specified for testing whether a user
may run a specific command.
o a new -U flag can be used in conjunction with "sudo -l" to allow
root (or a user with "sudo ALL") list another user's privileges.
* A new -g flag has been added to allow the user to specify a
primary group to run the command as. The sudoers syntax has been
extended to include a group section in the Runas specification.
* A uid may now be used anywhere a username is valid.
* The "secure_path" run-time Defaults option has been restored.
* Password and group data is now cached for fast lookups.
* The file descriptor at which sudo starts closing all open files is now
configurable via sudoers and, optionally, the command line.
* Visudo will now warn about aliases that are defined but not used.
* The -i and -s command line flags now take an optional command
to be run via the shell. Previously, the argument was passed
to the shell as a script to run.
* Improved LDAP support. SASL authentication may now be used in
conjunction when connecting to an LDAP server. The krb5_ccname
parameter in ldap.conf may be used to enable Kerberos.
* Support for /etc/nsswitch.conf. LDAP users may now use nsswitch.conf
to specify the sudoers order. E.g.:
sudoers: ldap files
to check LDAP, then /etc/sudoers. The default is "files", even
when LDAP support is compiled in. This differs from sudo 1.6
where LDAP was always consulted first.
* Support for /etc/environment on AIX and Linux. If sudo is run
with the -i flag, the contents of /etc/environment are used to
populate the new environment that is passed to the command being
run.
For full details see the ChangeLog file included with the release.
