Description of problem:
when using authconfig with --ldapserver option authconfig will modify
/etc/openldap/ldap.conf to include a [deprecated] HOST statement and will not
enable TLS_REQCERT or PORT 636 or other measures which would forcibly invoke
TLS.  Most annoyingly, authconfig will ignore existing [correct] URI lines.

Version-Release number of selected component (if applicable):
authconfig-4.6.10-rhel4.1
openldap-2.2.13-4

How reproducible:
Always

Steps to Reproduce:
1.  Set up an LDAP server
2.  run "authconfig --kickstart --enableldap --enableldapauth --ldapserver
SERVERNAME --enableldaptls"
  
Actual results:
authconfig modifies /etc/openldap/ldap.conf to include a HOST statement matching
SERVERNAME.  HOST is now deprecated according to the ldap.conf man page

Expected results:
authconfig should use the URI statement.  moreover, authconfig should check to
make sure that SERVERNAME is not already in URI format (eg. ldap://servername)
and convert it to such if needed.
At the very least authconfig should not modify a file that already contains a
URI using ldap:// or ldaps:// pointing to the same SERVERNAME. 

Additional info: 
if your server is configured to only accept connections with SSF such that
confidentiality is REQUIRED authconfig will cause your new client to not connect
to the server.
