I tested all of the above on a Ubuntu Hardy system and I have no
problems with bash completion and LDAP unix authentification. I think
this bug can be closed.

I discovered several bugs and saw several unexplained crashes when Ubuntu Hardy

When Ubuntu switched to 2.4.9, my OpenLDAP server and some clients became

Follow one of the HOWTOs on setting up LDAP distribution of user
accounts.
In my setup I use kerberos for the authentication whereas most online
articles describe how to shovel the authentication into LDAP too, but
this doesn't seem to matter. You'll see the problems either way.

According to http://www.debian-administration.org/articles/585, it seems
it's a bug in libnss-ldap:
This is a problem with libnss-ldap. try libnss-ldapd.
This came about when they changed from the openssl libraries to the gnutls
libraries
I have had the same problem on a Debian system.
I can confirm that changing to libnss-ldapd seems to solve the problem
here.
One configuration quirk: To control authorization per-host via LDAP, I
had the following in my old libnss-ldap /etc/ldap.conf:
nss_base_passwd
ou=People,dc=evalesco,dc=com?sub?|(host=eagle.rd)(host=\*.rd)(host=\*)
Maybe one of you can tell me how to reproduce this.
I.e. what packages do I need, how should I configure slapd and PAM? And
how do I get users into LDAP?
If I can reproduce it I'll try to debug the problem.

I rebuilt the bash package with --without-bash-malloc, and then tried
the bash executable from the bash-static/ directory. Same problem if run
from gdb. If I just start it with ./bash, and the enter compgen -u,
bash enters an endless loop, eats 100% CPU and won't react to SIGTERM; I
had to -KILL
I think the dcgettext is just libc finding the right translation for its
error message.
OK, final try for the test program. This is now almost a line-by-line
copy of the function in bash...
If this does not crash, the only idea I have left is to rebuild bash so
that it can be debugged...
**
Test program 3 runs fine, too. But I found out why all the test programs
run fine: They use the libc6 malloc(), while bash brings its own:
I did apt-get build-dep bash apt-get source bash, then
debian/rules in there. After that:
[EMAIL PROTECTED]:~/pwent-test/bash-3.2# grep start and end chunk
Yes, that's good. I was also wondering about the missing malloc calls :)
I think it would be best if you could take this to the bash-bug
mailinglist. They should know how best to debug this. You can do this
via the bashbug script.
You could also try the bash-static package which is build with

This gets stranger and stranger. :)
Maybe you could try this:
sudo apt-get install ltrace
ltrace -o ltrace.txt -S -n 4 -f bash -c 'compgen -u'
and post the log (maybe gzip it first :))
That should give much information. At least it does in my case...

Ouch, how could I have overseen such a good debugging tool for all these

Here is the ltrace, I just removed the plain usernames to protect the
innocent :)
** Attachment added: ltrace-bash-compgen-u-anonymized.txt.bz2
Yes, ltracte is quite handy at times.
It seems that the crash occurs in endpwent(), I added this to the test
program. Could you check whether it crashes now?

No, the test program did not crash, but behaves like the first one. I'm
sure many programs (like getent, ...) use this API, but the only thing
exhibiting this bug until now is the bash completion.
Attached is an ltrace of the pwent-test2.c program. I noticed that there
are none of the dcgettext()
Martin, can you try to compile and run the attached test program? It
should do pretty much what bash is doing when completing filenames.

Hi!
Your program works fine, lists all available users. In the same shell just
afterwards, hitting su - poTAB crashes the bash instance (bumps me back to
the Box I ssh'd into the server from).
BTW: I upgraded my real server over the weekend, and it exhibits the same
behaviour as the VM I first
Hm, strange...
You can get debug symbols for the Ubuntu packages, see:

gdb should pick them up automatically, IIRC.
