Description Kendal L. Montgomery 2003-02-19 19:55:45 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212

Description of problem:
Here's some background on my environment: it is a Red Hat Linux 8.0 (only
version tested) install , set up to authenticate against an openldap server on a
remote machine. Authconfig has been used to set up authentication, but nscd
service is not running (this was accidental and is not the actual problem).

When I try to install almost any 3rd party source rpms (in particular with files
owned / or with groups not known to my ldap server or local /etc/passwd
/etc/group files), I get a segmentation fault.  An example can be found at

I've done an rpm -vv --install <package> and normally will get output as such:

D: ============== kxmleditor-0.8.1-0.1.src.rpm
D: Expected size:      1038437 = lead(96)+sigs(100)+pad(4)+data(1038237)
D:   Actual size:      1038405
D: kxmleditor-0.8.1-0.1.src.rpm: MD5 digest: OK (fdee01fecd174d0f4b8a6c7b22a9dbb5)
D:      added source package [0]
D: found 1 source and 0 binary packages
D: Expected size:      1038437 = lead(96)+sigs(100)+pad(4)+data(1038237)
D:   Actual size:      1038405
Segmentation fault

I have also done some stracing as included in the attached file.

It's my assumption that for some reason, without nscd running, doesn't correctly
figure out that the user/group, "lvanek" in this case, does not exist and then
just dies.

I guess my complaint is that it should die a bit more gracefully with an
appropriate error message instead of a seg fault.  This problem really annoyed
me until somehow I figured out that nscd was in fact not running (my fault
totally), by pure luck.

On one other note, this bug *may* be loosely related to bug #84620.

How reproducible:

Steps to Reproduce:
1. Install RedHat 8.0
2. Set up authentication to LDAP server using authconfig, but don't select the
option to cache information. (or just simply disable nscd, like I accidentally did)
3. Try to install just about any 3rd party source rpm (that was build with the
files owned by a unknown user / and/or group.

Actual Results:  Segmentation Fault

Expected Results:  A useful error message, without having to do lots of
stracing, and a graceful exit.

Run nscd, required for statically linked executables like /bin/rpm
when using LDAP. This is a know LDAP problem.
