similar to: Patch to restrict other auth methods from allowing root password authentication

Attached is a patch that allows for an interactive Kerberos password change via keyboard-interactive, and also reports any banners received from krb5_g_i_c_p() (e.g., password expiration notification if you have krb5-1.2.x patched appropriately). This could probably be refactored a bit and probably done better, but I'm sending this in in case anyone finds it useful. The major drawback is

I have everything in place to move to a Samba/Heimdal/OpenLDAP auth database and have just discovered that some of the Windows products we use are required to run on a domain controller. Since domain sync doesn't work between Samba and NT4 it looks like I'm stuck: either ditch all the software we run on domain controllers, stay with our current 2-auth-db system, or move at least our

I took Markus Friedl's advice and set up a KbdintDevice for Kerberos password authentication/expiry. It took me a bit to wrap my head around privsep, but I think it's working properly (code stolen shamelessly from FBSD's PAM implementation :->). The hardest part was working out how to get the interaction between krb5_get_init_creds_password() (along with the prompter) to work

of the remotely connected socket is in in monitor_read(). The easiest way to pass them in would be to add fields to the Authctxt structure, which gets passed down into auth_krb5_password(), although possibly not the best. Perhaps using a prompter isn't the best way to go, either, I'm not sure. Ultimately, I'm simply looking for any pointers as to the best way to proceed, even if

This bug causes a segfault when compiled against heimdal, but not MIT krb5. Either way, I think this code is correct.

Hi All, While testing another patch, I found that I could not longer log in as root, even if PermitRootLogin was yes. It seems to be the following code in auth_password: $ cvs diff -r1.48 -r1.49 auth-passwd.c [snip] #ifndef HAVE_CYGWIN - if (pw->pw_uid == 0 && options.permit_root_login != PERMIT_YES) + if (pw->pw_uid == 0 && options.permit_root_login !=

Dear list, since the order of authentication and AFS token/KRB TGT forwarding changed (around 3.0), we have had problems with users accidentally overwriting their credentials from a "password" login with forwarded credentials. E.g. user A logs in as user B, but stays with the AFS permissions of user A. A workaround is to use "-k" on these sessions, but "it worked without

Hi all, among other things, we provide shell access to various unix based platforms for our students and university staff. Recently, there has been increasing number of root login attacks on one particular Tru64 machine running OpenSSH. The host is configured with "PermitRootLogin no" but every once in a while SIA auth with TCB enhanced security locks the root account. I suppose

I have tried this patch (against 3.5p1) and would very much like it to be in the OpenSSH 3.6p1 release, if possible: http://bugzilla.mindrot.org/show_bug.cgi?id=14 On that note, I'd like the Sun BSM patch to be included also, if possible. I have it working applied to 3.5p1: http://bugzilla.mindrot.org/show_bug.cgi?id=125 In fact, both patches work together, apparently. If I have any

Hi, as it turned out on the Cygwin mailing list, the special handling of empty password in auth-passwd.c when running under Windows NT results in problems. Cause: The authentication methode "none" calls auth_password() with an empty password. A piece of HAVE_CYGWIN code allows empty passwords even if PermitEmptyPasswords is set to "no". This in turn results in calling

This is about 90% of the core work. I omited a few files from the patch set since they are basicly small blocks of #ifndef HAVE_NEXT/#endif to get it to compile. Daimen, feel free to let me know what you applied and what your rejecting and why.. so I can work on cleaning things up. Andre, Only thing of note you may want to look into is NeXT does not use "ut_user" in it's lastlog.

Hi All. Attached is a patch against OpenBSD, based in part on the owl-always-auth patch. The idea is that the only way out of auth_passwd for the failure case is the "return 0" at the bottom. I don't know if this is a good way to do it or not, it's presented for discussion. Also, I don't think 3.6.1p2 is quite right WRT these timing issues (eg, you get a fast failure

All, We have recently updated our password aging to include setting inactivity days. We are running ossh 4.1p1 in a Solaris 8 environment. It appears that ossh isn't picking up on inactivity. Accounts that have been inactive still prompt to change passwords - if you telnet the same servers you get kicked out immediately. On the Solaris 9 servers running SUN's ssh the inactive accounts are

I am enclosing a context diff of the changes that I made to get openssh working on UWIN. UWIN is a UNIX operating system layer that runs on Win32 systems. For more information on UWIN go to http://www.research.att.com/sw/tools/uwin/. I also ran configure using -with-cppflags=-D_BSDCOMP=2. I don't know where that information would go with the source code. Let me know if you need more

Hello; Sorry for the crosspost/repost, but I am getting desparate here. I am having difficulties setting up ssh (ossh4.3p2 - NIS -Solaris8/Sparc) to authenticate and allow ossh access based on NIS netgroup. So, users and/or host should be from a valid netgroup triple, contained within the ossh servers .rhosts, .shosts, hosts.equiv and/or shosts.equiv. I am having alot of trouble getting NIS
