migration from Kerberos 4 to Kerberos 5
Hello, I have a few questions about migration to a new Kerberos version. In fact, the goal is to migrate a network with Kerberos 4 to the Kerberos 5(under Lin8x): 1) Do I have to reinstall Kerberos from the scratch or are there packages that allow to update the version? 2) What about the users that I created, are they still valid or will user information be lost. Part of the network uses already an LDAP directory, do I suppose this will not be a problem for this part, but in general, how can I migrate my user-accounts to the new version? 3) What about the clients, do I have to re-install the Kerberos-client on each workstation or can I use the "old" Kerberos clients? Could anybody answer my questions and perhaps give me some good hints for the migration respectively point me to some good documents? Thanx, CB ...

MIT Kerberos and Solaris 10 Kerberos
Greetings, everyone. We run a number of Solaris 8 systems using Sun's SEAM PAM implementation and MIT's Kerberos (which we're up to date on). We are starting to look at Solaris 10, and are hoping to move towards Sun's implementation of Kerberos. We are having a bit of trouble getting the two to talk properly, however. If we SSH (from production to test, for example) to a Solaris 8 machine, then we can rlogin (Kerberized) to the Solaris 10 machine and, from there, rlogin to a Sol8 machine again. If, however, we SSH directly to the Solaris 10 machine, we cannot rlogin to a Solaris 8 machine. Doing various experiments (for example, trying to ksu on the Sol 10 machine), the only error we ever get is: ksu WARNING: Your password may be exposed if you enter it here and are logged in remotely using an unsecure (non-encrypted) channel. Kerberos password for ux5p@ATCOTEST.CA: : ksu: Server not found in Kerberos database while geting credentials from kdc Authentication failed. Doing an rlogin to a Sol 8 machine gives no errors at all; it just quietly fails. The above error seems to indicate that the Solaris 10 Kerberos isn't passing the tickets to the Sol 8/MIT Kerberos servers (which, based upon certain differences, would not be a big surprise). Has anyone gotten this to work? The Sol 10 system is using the default Solaris 10 PAM implementation as well; not sure if this is part of the problem, but the configuration files are significantly different. Th...

OpenSSH, OpenAFS, Heimdal Kerberos and MIT Kerberos
Rather then implementing kafs in MIT Kerberos, I would like to suggest an alternative which has advantages to all parties. The OpenSSH sshd needs to do two things: (1) sets a PAG in the kernel, (2) obtains an AFS token storing it in the kernel. It can use the Kerberos credentials either obtained via GSSAPI delegation, PAM or other kerberos login code in the sshd. The above two actions can be accomplished by a separate process, which can be forked and execd by the sshd and passed the environment which may have a KREB5CCNAME pointing at the Kerberos ticket cache Other parameters such as the home directory could also be passed. This would then allow simple code in OpenSSH that does not depend on OpenAFS, Hiemdal or MIT code to fork/exec the process that does all the work. This would be called by the process that would eventially become the user's shell process and is run as the user. OpenSSH could be built on systems that may or may not have AFS installed and run on a system with or without AFS. The decision is based on the existence of the executable and any options in sshd_config. In its simplest form, all that is needed is: system("/usr/ssh/libexec/aklog -setpag") This is a little over simplified as there should be a test if the executable exists, processing of some return codes, making sure the environment is set, setting some time limit. etc. But the point is there is no compile dependence on OpenAFS, MIT or Hiemdal by the Op...

Replacing the system Kerberos with MIT Kerberos (from ports)
Is there a way to replace the Heimdal Kerberos libraries included in the FreeBSD base system with the MIT Kerberos libraries installed from the security/krb5 port? I know about the KRB5_HOME make option. I'm concerned about other "Kerberized" applications not working properly because they use the wrong client libraries, hence my desire to completely replace Heimdal with MIT Kerberos. The Heimdal Kerberos libraries shipped with the FreeBSD base system don't support TCP, so when a KDC replies to a client request with a response larger than the maximum UDP packet size, the Kerberos libraries return an error to the client instead of switching to TCP (which can handle large responses). I routinely encounter this problem when integrating FreeBSD servers and workstations into Windows Active Directory domains, where the KDC responses include additional authorization data derived from a security principal's group memberships: Samba's "net ads join" command fails with a "response too big for for UDP, retry with TCP" error when linked against Heimdal, but it succeeds (and everything else works properly) when linked against MIT Kerberos. (Note that I'm not willing to debate the semi-standard/non-standard inclusion of authorization data in a Kerberos ticket's PAC, nor am I willing to argue the applicability of the aforementioned operating systems to their assigned tasks.) Best wishes, Matthew ...

Kerberos Administration Protocol

RE: MIT Kerberos and Solaris 10 Kerberos #2
BTW, as a further clarification, the system was installed initially using our MIT Kerberos build (i.e. the same as we use on all of the Solaris 8 machines). I am now trying to get it to work with the Solaris 10 SEAM. One problem I see immediately (refreshing my memory with a couple quick tests) is that, when using the Sol10 SEAM to install the keytab, I immediately get: # kadmin -p rheilke/admin Authenticating as principal rheilke/admin@ATCOTEST.CA with password. Password for rheilke/admin@ATCOTEST.CA: kadmin: ktadd host/salty.atcotest.ca kadmin: Communication failure with server while changing host/salty.atcotest.ca's key kadmin: So, the Sol10 SEAM cannot seem to talk to the KDC.

Right. > Whoever told you 'ksu' was part of the encryption kit was mistaken, > ksu has never been part of SEAM. OK, thanks for that clarification. It was a bit of a surprise to me when I was told it was there. So, does the Solaris 10 SEAM have any functionality similar to ksu, or just the standard su command? > The encryption kit for Solaris 10 enhances the overall crypto > capabilities of the system, the only benefit Kerberos gets is > that it can support AES-256 with the S10 encryption kit. > Without the S10 encryption kit, the strongest AES crypto > available for Kerberos in S10 is AES-128.

That may be a good part of my problem. I added the inetd.conf entry for the old (MIT) eklogin, and ran inetconv. So, this is probably really confusing the system.

RE: MIT Kerberos and Solaris 10 Kerberos #6
OK, I think I have fixed the services. I have: # svcs -v | grep login online - 13:25:02 35 svc:/system/console-login:default online - 13:25:11 - svc:/network/login:eklogin online - 13:25:12 - svc:/network/login:klogin online - 13:25:12 - svc:/network/login:rlogin (Just to make sure, those ARE the correct versions? The ones I removed looked like: # svcadm disable svc:/network/klogin/tcp:default # svcadm disable svc:/network/eklogin/tcp:default The first entry in the svcs listing is, I assume, my root console login via the terminal server.) Or did I cancel the wrong two? If I use the MIT rlogin to go to another server, this fails (and no message gets logged on the KDC). I expect this is correct behaviour (needing the SEAM version). So, where do I find the Solaris 10 SEAM version of rlogin? The rlogin in /bin seems to be the old, un-Kerberized one, or is this actually a Kerberized one? In which case, it never seems to get a connection, and again, doesn't log anything on the KDC. I can use the Solaris 8/MIT rlogin to go from one of the old Solaris 8/MIT systems to the Solaris 10 box. Thanks again.
