After upgrading to the current Raw Hide (as of yesterday) and attempting to build from a spec file using rpmbuild, it complained "bad user/group" on one of the source files listed in the spec file. The user in question is listed in LDAP but not in the local passwd file. After adding the user to the local passwd file, the problem went away. jbj said I should report this under the openldap component rather than under rpm because "rpm doesn't know anything about LDAP" or some such thing. I suppose it could also be a glibc bug.
'Red Hat Raw Hide' refers to the development tree for Red Hat Linux. Red Hat Linux is no longer supported by Red Hat, Inc. If you are still running Red Hat Linux, you are strongly advised to upgrade to a current Fedora Core release or Red Hat Enterprise Linux or comparable. Some information on which option may be right for you is available at http://www.redhat.com/rhel/migrate/redhatlinux/. Red Hat apologizes that these issues were not resolved in a more timely manner. However, we do want to make sure that important don't slip through the cracks. If these issues are still present in a current release, such as Fedora Core 5, please move these bugs to that product and version. Note that any remaining Red Hat Raw Hide bugs will be closed as 'CANTFIX' on September 30, 2006. Thanks again for your help.
I no longer have any way of testing for this bug, and I suspect that nobody else cares about it, so closing it.
