1.1. LDAP/SSL Problems with Fedora Core 1

Immediately after upgrading from RH9 to FC1, I discovered I was unable to use SSL/TLS with Evolution to communicate with my LDAP server. Today I discovered I was also unable to communicate with my LDAP server with GQ and ldapsearch with SSL/TLS. The problem (as the CLI client told me) was the self-signed certificate. I did a little digging in Bugzilla and came up with this: Add to /etc/openldap/ldap.conf the line: 
TLS_REQCERT allow
and self-signed certs will again be usable. 
$ ldapsearch -v -d 10000 -x -H ldaps://ldapserver -b dc=example,dc=com objectclass=\*
ldap_initialize( ldaps://ldapserver )
TLS certificate verification: Error, self signed certificate
TLS: can't connect.
ldap_bind: Can't contact LDAP server (81)
        additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

1.2. Upgrading to Red Hat Enterprise Linux from Red Hat Linux

Extremely unofficial and unsupported! To convince Anaconda to allow you upgrade from a Red Hat Linux installation to an Enterprise Linux installation, remove the redhat-release file, so Anaconda won't know what version is actually installed and boot the installation media with the upgradeany flag.
