Philip,
I am no LDAP guru and my C programming is a little rusty, but this
simple patch seems to resolve the issue.
Another solution is to compile against openldap libraries which return
different return codes and do not exhibit this behaviour
(specifically they return LDAP_SUCESS)
bash-2.05# diff -c src/lookups/ldap.c-orig src/lookups/ldap.c
*** src/lookups/ldap.c-orig Tue Dec 5 15:46:33 2006
--- src/lookups/ldap.c Tue Dec 5 16:50:18 2006
***************
*** 864,870 ****
DEBUG(D_lookup) debug_printf("ldap_parse_result yielded %d: %s\n",
rc, ldap_err2string(rc));
! if (rc != LDAP_SUCCESS && rc != LDAP_SIZELIMIT_EXCEEDED)
{
*errmsg = string_sprintf("LDAP search failed - error %d:
%s%s%s%s%s",
rc,
--- 864,874 ----
DEBUG(D_lookup) debug_printf("ldap_parse_result yielded %d: %s\n",
rc, ldap_err2string(rc));
! if (rc != LDAP_SUCCESS && rc != LDAP_SIZELIMIT_EXCEEDED

! && rc != LDAP_RES_SEARCH_REFERENCE

{

rc,
Hope that helps. Feel free to include it in the source.
