True, didn't see that, thanks for pointing it out. But in the same section it presents a wrapper script that can be used in place of the real executable, as well as the recommendation to change it to SUID, as it will drop the privileges itself. That way, neither sudo nor ssh are needed.

But note that the recommended alternative to the above "workaround" is actually to install growisofs set-root-uid, in which case it will drop privileges prior accessing data or executing mkisofs in order to preclude unauthorized access to the data.
I have just found out that a project I have developed in ASP (ultradev) needs to be migrated to a unix server and won't be able to support asp. Can anyone point me in the right direction to see what my options are with Unix? I have never worked with or developed for a Unix box before.

Hi,
I am using rsync to copy files and links from one server to other (backup server).
The problem with rsync is that it is not copying the files and links in the order which i have mentioned.
It is sorting in alphabetical order before it is copying the files and links.

sssd-sudo - Configuring sudo with the SSSD back end
DESCRIPTION
This manual page describes how to configure sudo(8) to work with sssd(8) and how SSSD caches sudo rules.
CONFIGURING SUDO TO COOPERATE WITH SSSD
To enable SSSD as a source for sudo rules, add sss to the sudoers entry in nsswitch.conf(5).
For example, to configure sudo to first lookup rules in the standard sudoers(5) file (which should contain rules that apply to local users)
and then in SSSD, the nsswitch.conf file should contain the following line:
sudoers: files sss
More information about configuring the sudoers search order from the nsswitch.conf file as well as information about the LDAP schema that
is used to store sudo rules in the directory can be found in sudoers.ldap(5).
Note: in order to use netgroups or IPA hostgroups in sudo rules, you also need to correctly set nisdomainname(1) to your NIS domain name
(which equals to IPA domain name when using hostgroups).
CONFIGURING SSSD TO FETCH SUDO RULES
All configuration that is needed on SSSD side is to extend the list of services with "sudo" in [sssd] section of sssd.conf(5). To speed up
the LDAP lookups, you can also set search base for sudo rules using ldap_sudo_search_base option.
The following example shows how to configure SSSD to download sudo rules from an LDAP server.
[sssd]
config_file_version = 2
services = nss, pam, sudo
domains = EXAMPLE
[domain/EXAMPLE]
id_provider = ldap
sudo_provider = ldap
ldap_uri = ldap://example.com
ldap_sudo_search_base = ou=sudoers,dc=example,dc=com
When the SSSD is configured to use IPA as the ID provider, the sudo provider is automatically enabled. The sudo search base is configured
to use the compat tree (ou=sudoers,$DC).
THE SUDO RULE CACHING MECHANISM
The biggest challenge, when developing sudo support in SSSD, was to ensure that running sudo with SSSD as the data source provides the same
user experience and is as fast as sudo but keeps providing the most current set of rules as possible. To satisfy these requirements, SSSD
uses three kinds of updates. They are referred to as full refresh, smart refresh and rules refresh.
The smart refresh periodically downloads rules that are new or were modified after the last update. Its primary goal is to keep the
database growing by fetching only small increments that do not generate large amounts of network traffic.
The full refresh simply deletes all sudo rules stored in the cache and replaces them with all rules that are stored on the server. This is
used to keep the cache consistent by removing every rule which was deleted from the server. However, full refresh may produce a lot of
traffic and thus it should be run only occasionally depending on the size and stability of the sudo rules.
The rules refresh ensures that we do not grant the user more permission than defined. It is triggered each time the user runs sudo. Rules
refresh will find all rules that apply to this user, check their expiration time and redownload them if expired. In the case that any of
these rules are missing on the server, the SSSD will do an out of band full refresh because more rules (that apply to other users) may have
been deleted.
If enabled, SSSD will store only rules that can be applied to this machine. This means rules that contain one of the following values in
sudoHost attribute:
o keyword ALL
o wildcard
o netgroup (in the form "+netgroup")
o hostname or fully qualified domain name of this machine
o one of the IP addresses of this machine
o one of the IP addresses of the network (in the form "address/mask")
There are many configuration options that can be used to adjust the behavior. Please refer to "ldap_sudo_*" in sssd-ldap(5) and "sudo_*" in
sssd.conf(5).
