Description Gabriel Donnell 2003-06-19 04:39:42 UTC 
Description of problem:
LDAP does not work when TLS encryption is used on LDAP clients.

Version-Release number of selected component (if applicable):
2.0.27-8

How reproducible:
Always

Steps to Reproduce:
1. Configure a Red Hat Linux 9.0 LDAP server:
https://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-ldap-quickstart.html
2. Configure a Red Hat Linux 9.0 LDAP client with TLS encryption disabled:
https://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-ldap-pam.html
3. If no user accounts were added to the LDAP database with the migration tools,
   then added a test user account.
4. Create a local home directory for the LDAP user on the LDAP client host.
5. Confirm there is no local account for the LDAP user on the LDAP client host.
6. Log in without GDM (su, ssh, a tty login screen, etc) to confirm it works.
7. Enable TLS encryption on the LDAP client host.
8. Log in without GDM (su, ssh, a tty login screen, etc) to verify failure.

Actual results:
Error message below is printed by ldap client or in /var/log/messages file.
ldap_starttls_s: Connect error

Expected results:
TLS encryption to work with LDAP clients.

Additional info:
An excerpt from the /var/log/messages file on the LDAP client system is
attached.

The several lines show LDAP TLS start failure messages.  Then they are followed
by successful testuser0 log in sessions from the login (tty1), su, and sshd
utilities.

Do not use GDM to log in to the LDAP client host because it does not work.
I reported this in the 97676 ticket.
Comment 3 Gabriel Donnell 2003-06-19 08:23:59 UTC 
Hello,

I resolved the problem.  I followed the resolution provided by Nalin Dahyabhai
in the 51352 ticket.  I had to regenerate the /usr/share/ssl/certs/slapd.pem
file with the LDAP server host name that the LDAP client was configured to use.
I did that earlier, but forgot to change the group and permissions so the ldapd
user could read the file.

Sorry, for submitting this ticket.  I did not read and follow the resolution
in the 51352 ticket carefully.

This information should be documented.  May be I over looked it.  I did not
see this in the Red Hat Reference Guide or DAP Linux HOWTO.
