Hi,

  While chasing referrals in request.c's ldap_chase_referral,
we found the new 'ref' being parsed out and encoded into a new
ber does not work right all the time unless we call 
ldap_pvt_hex_unescape on the 'ref' first. I am not sure if this
is a problem because we often get back a huge list of referrals
from a search request or trigger referrals on top of previous 
referral. 

Thanks
