An assortment of commands and tools related to AFS authentication sorted by authentication system.
## [[KaServer]] -- AFS version of Kerberos V4
The klog command (and kpasswd too) try several [[StringToKey]] functions.
- klog -- authentication with [[KaServer]] by getting AFS service tickets and sending them to the (kernel) [[CacheManager]]. Can save the TGT in a file compatible with kinit (V4) as a non-default option.
- tokens -- displays AFS service tickets (tokens) held by the [[CacheManager]].
- kpasswd -- change password in [[KaServer]]
- kas -- administrative interface to [[KaServer]]
- inetd -- passes authentication information to network servers. See [inetd ](http://www.cs.rose-hulman.edu/docs/afs-doc/html/AdminRef/auarf179.htm#HDRINETD). [Avoid](http://lists.openafs.org/pipermail/openafs-devel/2002-January/002351.html).
- r\* commands -- passes authentication information between trusting hosts (over a secure network). See [Remote Services](http://www.cs.rose-hulman.edu/docs/afs-doc/html/AdminGd/auagd007.htm#HDRWQ78). [Avoid](http://lists.openafs.org/pipermail/openafs-devel/2002-January/002351.html) and [thread](http://lists.openafs.org/pipermail/openafs-devel/2002-January/002372.html). These are not built by default in [[OpenAFS]] unless --enable-insecure is specified.
## [[KerberosIV]] -- MIT reference for V4
- kinit -- authenticates using standard UDP port 750. Also works with [[KaServer]] but doesn't get AFS service tickets (tokens).
- ktadd -- adds a new key/principal to [[KeyDistributionCenter]] (KDC) (or changes the key if it already exists?)
## [[KerberosV]] -- MIT reference for V5
There are more types of [[StringToKey]] functions in V5.
[[CharlesClancy]] posted a Perl [script](http://lists.openafs.org/pipermail/openafs-info/2002-January/003060.html) that provides a kas interface to kadmin, so that existing scripts (and users) that use kas can easily work in a K5 environment.
- kinit -- authenticates using standard UDP port 88. Works with DCE, [[HeimdalKTH]] and [[ActiveDirectory]] (maybe?).
- klist -- displays contents of ticket cache.
- ktadmin
- ktadd -- add a principal
ktadd -k /etc/krb5/keytab -e des-cbc-crc:v4 .EDU
- ktremove -- removes a principal from the KDC
- kprop
## [[KerberosDCE]] -- DCE version of V5
- kinit -- authenticates to DCE Security Server and also obtains authorization informaion (groups) from the DCE Privilege Server.
- chpass -- change password
- dcecp -- admin suite
## [[HeimdalKTH]] -- International version of Kerberos V5
Here's some [mail](http://lists-openafs.central.org/pipermail/openafs-info/2001-April/000591.html) from [[DerrickBrashear]] for using [[HeimdalKTH]] for AFS authentication. An updated version of this document can be found [here](http://lost-contact.mit.edu/afs/net/project/afs32/andrew.cmu.edu/usr/shadow/ka2heim.txt):
The kas wrapper mentioned above maybe useful for Heimdal environments too.
- afslog
- ktutil -- for example to create a [[KeyFile]] for AFS servers you can use this sequence
`ktutil -k keytab.afs get afs@MY.REALM`
`ktutil copy FILE:keytab.afs AFSKEYFILE:/usr/vice/etc/KeyFile`
It can also convert from `srvtab` format.
- hprop -- initializes a database from [[KaServer]] (?)
- ipropd -- propagates KDC databases between master and slave servers?
## [[ActiveDirectory]] -- Microsoft version of Kerberos V5
## Other commands
- aklog -- converts V5 TGT to AFS service tickets and gives them to the [[CacheManager]]. Is this part of the standard MIT K5 distribution?
- ka-forwarder -- allows klog to work in V5 environments, not needed if you are willing to use kinit/aklog. This is a [[HeimdalKTH]] tool?
- asetkey -- converts a V5 keytab file containing the AFS service ticket key and stores it into a [[KeyFile]] which AFS servers understand.
- fakeka
- r\* commands -- where to get safe kerberized versions?
- pts -- suite of commands for accessing the [[PtServer]] to manage AFS groups in all authentication environments.
- uss -- user creation tool. It is [documented](http://www.openafs.org/pages/doc/AdminReference/auarf242.htm#HDRUSS_INTRO) in the admin guide. It has some support for alternate authentication systems, but probably works best in [[KaServer]] environments.
