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 ...

replacing Heimdal with MIT Kerberos, and Kerberos key attributes in LDAP back-end
Hi all Since we are migrating from Debian to RedHat, we are considering replacing our Heimdal Kerberos server (with LDAP back-end) with an MIT Kerberos server (again with LDAP back-end) since RedHat packages are only available for MIT Kerberos. In order to make this migration/upgrade as transparent as possible for our users, we want to convert all the necessary info in the Heimdal back-end to the MIT back-end. Are there any pointers available for this kind of operation? E.g. things like conversion tables mapping the corresponding Kerberos-specific LDAP attributes? Or even scripts?...

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 Sola...

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 ...

RE: MIT Kerberos and Solaris 10 Kerberos #6
OK, I think I have fixed the services.

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.

It was a bit of a surprise to me when I was told it was there.

A Query on MIT Kerberos code base and latest RFC on Kerberos ?
Hi All, I have a small query regarding MIT Kerberos and it will be kind if anyone can address it. I wanted to know whether the latest RFC's: RFC 4120 - The Kerberos Network Authentication Service (V5) RFC 4121 - The Kerberos Version 5 Generic Security Service Application Program Interface (GSS-API) Mechanism: Version 2 ...are already a part of MIT Kerberos code base or is it schedule to be a part for MIT code base ? If so what will be the rough time frame. � Thanks n regards, Prashant ________________________________________________ Kerberos mailing list Kerberos@mit.edu...

Important Notice Regarding Kerberos 4 Support in MIT Kerberos
This comes from a message distributed to another list but I thought it might be useful here too. On January 27th of this year, the MIT Kerberos Development team announced plans to phase out support for Kerberos 4 in MIT Kerberos, including v4 support in Kerberos for Macintosh and Kerberos for Windows. We strongly recommend that all sites currently using Kerberos 4 migrate their services and users to Kerberos 5 as soon as possible. The MIT Kerberos team is making substantial changes to the client-side initial ticket acquisition support in the next release of Kerberos. These changes will im...

Heimdal or MIT kerberos
Hi, I m not sure which kerberos I should use. With Heimdal, it is a thread-safe implementation, while MIT's kerberos is not. Please correct me if I m wrong, it appears that there is more applicatoins support MIT kerberos than Heimdal. I basically want to use kerbeors as a SSO server and allows various internet/network service to securely authenticate with users. Applications I would like to be kerberized is samba, apache, email (ldap).. So which kerberos should be used to avoid future difficulty of integration with the above application? thanks sam On Mon, 04 Oct 2004 10:55:49 +...

RE: MIT Kerberos and Solaris 10 Kerberos
Wohoo! I read the man page for rlogin, and it is both the old rlogin, and the new (or something like that). Seems that you just have to give it the correct switches, and it Kerberizes the command. So, I did: rlogin -AF <sol8server> and it works! Thank you to Wyllys for all of your help. Now I'm going to try installing from scratch, and make sure I do the build properly. One question left for Wyllys before I do, though. Since ksu doesn't exist in the Solaris SEAM product, is our only option su?

I'll look into this further. As far as a co-worker is concerned (and in our environment, I can see his point), this would be a show stopper. We use ksu for all sorts of things, including giving DBA's access to Oracle ID's. Thanks again for all of the help. I'll go through the su and pam.conf man pages, and see if I can figure it out.

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 th...

MIT Kerberos KDC & W2K Client: Changing expired password issueMIT Kerberos KDC & W2K Client: Changing expired password issue
Hi, I also experienced the same problem as William G.Zereneh (http://mailman.mit.edu/pipermail/kerberos/2004-May/005341.html). I'm able to change the password using ctrl-alt-del, but when the password is expired and windows asks me to change the password, I encountered "Domain MIT.REALM.COM is not available" error. As I sniff the packet, it noticed that it sent a CLDAP query message with filter: (&(DnsDomain = MIT.REALM.COM)(Host = myhostname)(NtVer=\006) which is returned NULL by my _ldap._tcp.dc._msdcs.REALM.MIT.COM How to resolve this problem ? maybe there's a missin...
