Description of problem:


I get a segv when I open multiple terminal windows. I use the SSH
client from SSH Communications which allows you to fire off multiple
terminal windows within the same one connection. 

This ONLY happens with using pam_ldap. I have tested with the
openssh-3.6.1p2-33.30.3.test RPM as well and still get this behavior. 

This ONLY happens if I connect to the server as root. If I connect as
a non-priv users, everything works fine.

without privilege separation: sshd crashes when I open the 3rd window
with privilege separation: 2nd window causes segv

An strace shows a SEGV and I can send traces of whatever. 

Version-Release number of selected component (if applicable):
openssh-3.6.1p2-33.30.3

How reproducible:
Always

Steps to Reproduce:
1. use authconfig to enable ldap accounts and auth
2. ssh in as root with windoze GUI client
3. launch multiple windows, terminal or sftp.
    

Actual Results:  strace shows sigsegv

Expected Results:  work normally

Could you attach the strace log and could you get a backtrace of the
SEGV possibly with installed openssh-debuginfo package?


Comment 2 Tomas Mraz 2005-03-15 08:51:57 UTC
Can you check if nss_ldap-207-15 from
http://people.redhat.com/nalin/test/ resolves this?
