This problem was reported by PNNL, +and is now fixed. + +Any Kerberized application can now use a forwarded TGT to establish a +DCE context, or can use a previously established DCE context. This is +both a functional improvement and a performance improvement. + +BACKGROUND + +The MIT Kerberos 5 Release 1.x and DCE 1.1 can interoperate in a +number of ways. This is possible because: + + o DCE used Kerberos 5 internally. Based on the MIT code as of beta 4 + or so, with additional changes. + + o The DCE security server can act as a K5 KDC, as defined in RFC 1510 + and responds on port 88. + + o On the clients, DCE and Kerberos use the same format for the ticket + cache, and then can share it. The KRB5CCNAME environment variable points + at the cache. + + o On the clients, DCE and Kerberos use the same format for the srvtab + file. DCE refers to is a /krb5/v5srvtab and Kerberos as + /etc/krb5.keytab. They can be symlinked. + + o MIT has added many options to the krb5.conf configuration file + which allows newer features of Release 1.0 to be turned off to match + the earlier version of Kerberos upon which DCE is based. + + o DCE will accept a externally obtained Kerberos TGT in place of a + password when establishing a DCE context. + +There are some areas where they differ, including the following: + + o Administration of the database and the keytab files is done by the + DCE routines, rather the the Kerberos kadmin. + + o User password changes must be done using the DCE commands. Kpasswd + does not work. (But there are mods to Kerberos to use the v5passwd + with DCE. + + o DCE goes beyond authentication only, and provides authorization via + the PAC, and the dce-ptgt tickets stored in the cache. Thus a + Kerberos KDC can not act as a DCE security server. + + o A DCE cell and Kerberos realm can cross-realm authenticate, but + there can be no intermediate realms. (There are other problems + in this area as well. But directly connected realms/cells do work.) + + o You can't link a module with the DCE library and the Kerberos + library. They have conflicting routines, static data and structures. + +One of the main features of DCE is the Distributed File System +DFS. Access to DFS requires authentication and authorization, and when +one uses a Kerberized network utility such as telnet, a forwarded +Kerberos ticket can be used to establish the DCE context to allow +access to DFS. + + +NEW TO THIS RELEASE + +This release introduces sharing of a DCE context, and PAG, and allows +any Kerberized application to establish or share the context. This is +made possible by using an undocumented feature of DCE which is on at +least the Transarc and IBM releases of DCE 1.1. + +I am in the process of trying to get this contributed to the general +DCE 1.2.2 release as a patch, so it could be included in other vendors +products. HP has expressed interest in doing this, as well as the +OpenGroup if the modification is contributed. You can help by +requesting Transarc and/or IBM to submit this modification to the +OpenGroup and ask your vendor to adopt this modification. + +The feature is a modification to the setpag() system call which will +allow an authorized process to set the PAG to a specific value, and +thus allow unrelated processes to share the same PAG. + +This then allows the Kerberized daemons such as kshd, to exec a DCE +module which established the DCE context. Kshd then sets the +KRB5CCNAME environment variable and then issues the setpag() to use +this context. This solves the linking problem. This is done via the +k5dfspag.c routine. + +The k5dfspag.c code is compiled with the lib/krb5/os routines and +included in the libkrb5. A daemon calls krb5_dfs_pag after the +krb5_kuserok has determined that the Kerberos principal and local +userid pair are acceptable. This should be done early so as to give +the daemon access to the home directory which may be located on DFS. +If the .k5login file is used by krb5_kuserok it will need to be +accessed by the daemon and will need special ACL handling. + +The krb5_dfs_pag routine will exec the k5dcecon module to do all the +real work. Upon return, if a PAG is obtained, krb5_dfs_pag with set +the PAG for the current process to the returned PAG value. It will +also set the KRB5CCNAME environment as well. Under DCE the PAG value +is the nnnnnnn part of the name of the cache: +FILE:/opt/dcelocal/var/security/creds/dcecred_nnnnnnnn. + +The k5dcecon routine will attempt to use TGT which may have been +forwarded, to convert it to a DCE context. If there is no TGT, an +attempt will be made to join an existing PAG for the local userid, and +Kerberos principal. If there are existing PAGs, and a forwarded TGT, +k5dcecon will check the lifetime of the forwarded TGT, and if it is +less than the lifetime of the PAG, it will just join the PAG. If it +is greater, it will refresh the PAG using the forwarded TGT. +This approach has the advantage of not requiring many new tickets from +having to be obtained, and allows one to refresh a DCE context, or use +an already established context. + +If the system also has AFS, the AFS krb5_afs_pag should be called +after the krb5_dfs_pag, since cache pointed at via the KRB5CCNAME may +have changed, such as if a DFS PAG has been joined. The AFS code does +not have the capability to join an existing AFS PAG, but can use the +same cache which might already had a +afsx/<afs.cell.name>@<k5.realm.name> service ticket. + + +WHAT'S IN THIS RELEASE + +The k5prelogin, k5dcelogin, k5afslogin (with ak5log) were designed to +be slipped in between telnetd or klogind and login.krb5. They would +use a forwarded Kerberos ticket to establish a DCE context. They are +the older programs which are included here. They work on all DCE +platforms, and don't take advantage of the undocumented setpag +feature. (A version of k5dcelogin is being included with DCE 1.2.2) + +K5dcecon is the new program which can be used to create, update or +join a DCE context. k5dcecon returns KRB5CCNAME string which contains +the PAG. + +k5dfspag.c is to be built in the MIT Kerberos 5 release 1.0 patchlevel +1 and added to the libkrb5. It will exec k5dcecon and upon return set +the KRB5CCNAME and PAG. Mods to Kerberized klogind, rshd, telnetd, +ftpd are available to use the k5dfspag. + +Testpag.c is a test programs to see if the PAG can be set. + +The cpwkey.c routine can be used to change a key in the DCE registry, +by adding the key directly, or by setting the salt/pepper and password +or by providing the key and the pepper. This could be useful when +coping keys from a K4 or AFS database to DCE. It can also be used when +setting a DCE to K5 cross-cell key. This program is a test program +For mass inserts, it should be rewritten to read from stdin. + +K5dcelogin can also be called directly, much like dce_login. +I use the following commands in effect do the same thing as dce_login +and get a forwardable ticket, DCE context and an AFS token: + + #!/bin/csh + # simulate a dce_login using krb5 kinit and k5dcelogin + # + setenv KRB5CCNAME FILE:/tmp/krb5cc_p$$ + /krb5/bin/kinit -f + exec /krb5/sbin/k5dcelogin /krb5/sbin/k5afslogin /bin/csh + #exec /krb5/sbin/k5dcelogin /bin/csh + +This could be useful in a mixed cell where "AS_REQ" messages are +handled by a K5 KDC, but DCE RPCs are handled by the DCE security +server. + +TESTING THE SETPAG + +The krb5_dfs_pag routine relies on an undocumented feature which is +in the AIX and Transarc Solaris ports of DCE and has been recently +added to the SGI version. To test if this feature is present +on some other DFS implementation use the testpag routine. + +The testpag routine attempts to set a PAG value to one you supply. It +uses the afs_syscall with the afs_setpag, and passes the supplied +PAG value as the next parameter. On an unmodifed system, this +will be ignored, and a new will be set. You should also check that +if run as a user, you cannot join a PAG owned by another user. +When run as root, any PAG should be usable. + +On a machine with DFS running, do a dce_login to get a DCE context and +PAG. ECHO the KRB5CCNAME and look at the nnnnnnnn at the end. It +should look like an 8 char hex value, which may be 41ffxxxx on some +systems. + +Su to root and unsetenv KRB5CCNAME. Do a testpag -n nnnnnnnn where +nnnnnnnn is the PAG obtained for the above name. + +It should look like this example on an AIX 4.1.4 system: + + pembroke# ./testpag -n 63dc9997 + calling k5dcepag newpag=63dc9997 + PAG returned = 63dc9997 + +You will be running under a new shell with the PAG and KRB5CCNAME set. +If the PAG returned is the same as the newpag, then it worked. You can +further verify this by doing a DCE klist, cd to DFS and a DCE klist +again. The klist should show some tickets for DFS servers. + +If the PAG returned is not the same, and repeated attempts show a +returned PAG decremented by 1 from the previous returned PAG, then +this system does not have the modification For example: + + # ./testpag -n 41fffff9 + calling k5dcepag newpag=41fffff9 + PAG returned = 41fffff8 + # ./testpag -n 41fffff9 + calling k5dcepag newpag=41fffff9 + PAG returned = 41fffff7 + +In this case the syscall is ignoring the newpag parameter. + +Running it with -n 0 should get the next PAG value with or without +this modification. + +If the DFS kernel extensions are not installed, you would get +something like this: + + caliban.ctd.anl.gov% ./testpag -n 012345678 + calling k5dcepag newpag=012345678 + Setpag failed with a system error + PAG returned = ffffffff + Not a good pag value + +If you DFS implementation does not have this modification, you could +attempt to install it yourself. But this requires source and requires +modifications to the kernel extensions. At the end of this note is an +untested sample using the DCE 1.2.2 source code. You can also contact +your system vendor and ask for this modification. + +UNICOS has a similar function setppag(newpag) which can be used to set +the PAG of the parent. Contact me if you are interested. + +HOW TO INSTALL + +Examine the k5dfspag.c file to make sure the DFS syscalls are correct +for your platform. See the /opt/dcelocal/share/include/dcedfs/syscall.h +on Solaris for example. + +You should build the testpag routine and make sure it works before +adding all the other mods. If it fails you can still use the klogind +and telnetd with the k5prelogin and k5dcelogin code. + +If you intend to install with a prefix other than /krb5, change: +DPAGAIX and K5DCECON in k5dfspag.c; the three references in +k5prelogin.c; and the DESTDIR in the Makefile. + +Get k5101.cdiff.xxxxxx.tar file and install the mods for ANL_DFS_PAG +and ANL_DCE to the MIT Kerberos 5 source. These mods turn on some DCE +related changes and the calls to krb5_dfs_pag. + +Symlink or copy the k5dfspag.c to the src/lib/krb5/os directory. + +Add the -DANL_DFS_PAG and -DANL_DCE flags to the configuration. + +Configure and Build the Kerberos v5. + +Modify the k5dce Makefile for your system. + +Build the k5dcecon and related programs. + +Install both the MIT Kerberos v5 and the k5dcecon and dpagaix if AIX. + +The makefile can also build k5dcelogin and k5prelogin. The install +can install k5dcelogin, k5prelogin and update the links for login.krb5 +-> k5prelogin and moving login.krb5 to login.k5. If you will be using +the k5dcecon/k5dfspag with the Kerberos mods, you don't need +k5prelogin, or the links changed, and may not need k5dcelogin. + +Note that Transarc has obfuscated the entries to the lib, and +the 1.0.3a is different from the 1.1. You may need to build two +versions of the k5dcelogin and/or k5dcecon one for each. + +AIX ONLY + +The dpagaix routine is needed for AIX because of the way they do the +syscalls. + +The following fix.aix.libdce.mk is not needed if dce 2.1.0.21 +has been installed. This PTF exposed the needed entrypoints. + +The fix.aix.libdce.mk is a Makefile for AIX 4.x to add the required +external entry points to the libdce.a. These are needed by k5dcecon +and k5dcelogin. A bug report was submitted to IBM on this, and it was +rejected. But since DCE 1.2.2 will have a k5dcelogin, this should not +be needed with 1.2.2 + +Copy /usr/lib/libdce.a to /usr/libdce.a.orig before starting. Copy the +makefile to its own directory. It will create a new libdce.a which you +need to copy back to /usr/lib/libdce.a You will need to reboot the +machine. See the /usr/lpp/dce/examples/inst/README.AIX for a similar +procedure. IBM was not responsive in a request to have these added. + +UNTESTED KERNEL EXTENSION FOR SETPAG + +*** src/file/osi/,osi_pag.c Wed Oct 2 13:03:05 1996 +--- src/file/osi/osi_pag.c Mon Jul 28 13:53:13 1997 +*************** +*** 293,298 **** +--- 293,302 ---- + int code; + + osi_MakePreemptionRight(); ++ /* allow sharing of a PAG by non child processes DEE- 6/6/97 */ ++ if (unused && osi_GetUID(osi_getucred()) == 0) { ++ newpag = unused; ++ } else { + osi_mutex_enter(&osi_pagLock); + now = osi_Time(); + soonest = osi_firstPagTime + +*************** +*** 309,314 **** +--- 313,319 ---- + } + osi_mutex_exit(&osi_pagLock); + newpag = osi_genpag(); ++ } + osi_pcred_lock(p); + credp = crcopy(osi_getucred()); + code = osi_SetPagInCred(credp, newpag); + +Created 07/08/96 +Modified 09/30/96 +Modified 11/19/96 +Modified 12/19/96 +Modified 06/20/97 +Modified 07/28/97 +Modified 02/18/98 + + Douglas E.
