RE: referral mess in HEAD

["Howard Chu" <hyc@highlandsun.com>]

Now that the client hangs appear to be sorted out, there's something else
flaky going on. Using the same test tree as before, if I try to bind to the
server using a subordinate DN, the bind is referred incorrectly.

ldapsearch -x -C -b o=airbus -D cn=joe,ou=hamburg,o=eg,o=airbus -w secret -H
ldap://:20389 -d 7

The server's response to the bind is:

ber_get_next
ldap_read: want=9, got=9
  0000:  30 41 02 01 01 61 3c 0a  01                        0A...a<..
ldap_read: want=58, got=58
  0000:  0a 04 0d 6f 3d 65 67 2c  6f 3d 61 69 72 62 75 73   ...o=eg,o=airbus
  0010:  04 00 a3 26 04 24 6c 64  61 70 3a 2f 2f 31 32 37   ...&.$ldap://127
  0020:  2e 30 2e 30 2e 31 3a 31  30 33 38 39 2f 6f 3d 65   .0.0.1:10389/o=e
  0030:  67 2c 6f 3d 61 69 72 62  75 73                     g,o=airbus
ber_get_next: tag 0x30 len 65 contents:
ldap_read: message type bind msgid 1, original id 1
ber_scanf fmt ({iaa) ber:
ber_scanf fmt ({v}) ber:
ldap_chase_v3referrals
ldap_url_parse_ext(ldap://127.0.0.1:10389/o=eg,o=airbus)
re_encode_request: new msgid 2, new dn <o=eg,o=airbus>
ber_scanf fmt ({it) ber:
ber_scanf fmt ({ia) ber:
re_encode_request new request is:
ldap_chase_v3referral: msgid 1, url "ldap://127.0.0.1:10389/o=eg,o=airbus";
....

and eventually the bind request is re-sent as

ber_flush: 33 bytes to sd 4
