I think I understand that. I'll have to research it more.

I did run into a problem with ldap though. I've been getting the chase
referrals error and have been messing with the chase_referrals variable, but
after turning debug on, it looks like it is building the chase URL
incorrectly.

postmap: dict_ldap_debug: ber_scanf fmt ({v}) ber:
postmap: dict_ldap_debug: ldap_chase_v3referrals
postmap: dict_ldap_debug: ldap_url_parse_ext(
ldap://example.com.com/dc=example.com,dc=com)
postmap: dict_ldap_debug: re_encode_request: new msgid 3, new dn <dc=
example.com,dc=com>
postmap: dict_ldap_debug: ber_scanf fmt ({it) ber:
postmap: dict_ldap_debug: ber_scanf fmt ({ae) ber:
postmap: dict_ldap_debug: ldap_chase_v3referral: msgid 2, url "
ldap://example.com.com/dc=example.com,dc=com"

Any idea how I can get around this? Can I specifically list the chase url
in the config file? I didn't see an option for it in the ldap_table man
page.

Any ideas?

Thanks,

GT
