Description Norman Elton 2007-03-27 16:18:28 EDT
Description of problem:

I have a fresh installation of RHEL5. Using authconfig, I've pointed the
installation at our LDAP server, which is running SSL/TLS. Everything gets
configured correctly, I can id/groups a particular user, login, etc.

When I go to install NTP (yum install ntp), the installation hangs. If I install
the RPM manually, with debugging enabled, I see that the process hangs at:

D:   install: %pre(ntp-4.2.0.a.20040617-4.EL4.1.x86_64) execv(/bin/sh) pid 3165
+ /usr/sbin/groupadd -g 38 ntp

If I execute the groupadd command by hand, it works fine. Inside the RPM
installation; however, it's hanging. In /var/log/secure, I see...

groupadd[3166]: nss_ldap: reconnecting to LDAP server (sleeping 4 seconds)...
rheltest groupadd[3166]: nss_ldap: reconnecting to LDAP server (sleeping 8

If I disable TLS and use straight LDAP, everything works as expected.

Any ideas?

I am not able to reproduce this bug on my RHEL5 box. Could you please provide me
your ldap and nss configuration? Namely: /etc/ldap.conf, /etc/nsswitch.conf and
/etc/openldap/* (without your TLS certificates/keys, of course).

I am also a bit confused why your yum tries to install RHEL4 package
(ntp-4.2.0.a.20040617-4.EL4.1.x86_64) instead of the RHEL5 one
(ntp-4.2.2p1-5.el5). And you filled your HW is i686, but yum installs x86_64
package... Could you please double check your yum configuration or the bug
report header?
