Description Marc Wallman 2003-12-09 21:25:01 UTC
Description of problem:
Sendmail segfaults when attempting to route mail using LDAP. This
problem happens every time. It does work under Red Hat 8.

Version-Release number of selected component (if applicable):
* sendmail-8.12.10-1
* OS is RHEL 3ES.
* OpenLDAP server runs 2.1.22
* Works with RH 8 and sendmail-8.12.8-9.80

How reproducible:
Can reproduce every time.

Steps to Reproduce:
1. Enable ldap mail routing in sendmail using the default
   sendmail schema / routing rules.
2. Send a test message to an address in your ldap database.
3. Run ltrace on the process accepting the incoming message
   and watch the output to see that the segfault comes after
   the ldapbind.
Actual results:
When submitting the message using telnet, the connection is
immediately closed after inputing the "rcpt to:" line. A ltrace (or
strace) on the process accepting the email shows the process
terminating with a segmentation fault. Non-LDAP based mail routing
works fine.

Expected results:
LDAP bind should succeed. Mail should be routed for valid users.
Notification should be given to the sending client when an invalid
"rcpt to:" line is entered.

Here are the last few lines of an ltrace showing the sendmail process
accepting an incoming message seg faulting:

Comment 6 Marc Wallman 2003-12-29 21:55:06 UTC
I see a number of folks joined the CC list. Is anybody at RH working
on this? Is it known to be working anywhwere? This problem occurs for
me every time and I have an almost identical configuration running
under RH 8 that works fine. I think this is a bug, not a configuration

Comment 7 Jp Robinson 2004-01-09 15:07:58 UTC
Please be assured that we are working on it, however, please realize
the some of this involves internal discussion and not all comments are


Comment 13 Marc Wallman 2004-01-14 12:11:46 UTC

Will the packages you listed in comment #12 be released as an errata 
package to the relevant RHN channels?

FYI, I also found that replacing the openldap-* packages shipped by 
red hat with openldap 2.1.22 packages fixes the sendmail ldap routing 
problem as well.

Comment 14 Marc Wallman 2004-01-16 22:55:59 UTC
I've been running the packages listed in comment #12 in production for
the last 36 hours or so and they are doing just fine.

Comment 35 Thomas Woerner 2004-02-27 09:15:19 UTC
The package (#34) will be in the next update.

The link provided at: http://people.redhat.com/twoerner/SRPMS/3.0E/sendmail-8.12.11
-3.src.rpm does not contain the SRPM package. Can you please correct?

Comment 39 Oliver Jones 2005-04-12 12:29:25 UTC
I have the same problem with my RHEL 2.1 server (trying to enable LDAP Aliases
etc).  Sendmail SEGV's after the RCPT TO: envelope header.  

I must admit however that I'm using a rebuild of the RHL 7.3 sendmail RPM on
this server though.  The main reason for that was to get SSL support as the
original RHEL 2.1 sendmail didn't link to OpenSSL.

Is there a build of sendmail-8.12.11 available for RHEL 2.1?
