OpenLDAP 2.3.19 + syncprov.c from HEAD, BDB db42-4.2.52_3, FreeBSD 4.10.

Refer to ftp://ftp.openldap.org/incoming/dave-horsfall-060217.tar.gz,
containing "slapd.conf" (obvious) and "gdb.slapd" (a back-trace of SLAPD).

LDAPSEARCH returns a result then hangs.

slapd.conf:

(Please see file slapd.conf in dave-horsfall-060217.tar.gz)

Query:

ldapsearch -h localhost -b dc=AdminView
"(&(objectclass=ciapplication)(ciapp=orc
k))" ciAppType

Output:

# extended LDIF
#
# LDAPv3
# base <dc=AdminView> with scope subtree
# filter: (&(objectclass=ciapplication)(ciapp=orck))
# requesting: ciAppType 
#

# orck, au.cordoors.dev
dn: ciApp=orck,dc=au,dc=cordoors,dc=dev
ciAppType: MER

(Force a core-dump; log merely shows all meta-dbs being searched)

Edit out proxycache, and find I can't stop SLAPD.  Enable set-uid cores,
and do it in.

GDB (of SLAPD):

Result of search with proxycache commented out:

# extended LDIF
#
# LDAPv3
# base <dc=AdminView> with scope subtree
# filter: (&(objectclass=ciapplication)(ciapp=orck))
# requesting: ciAppType 
#

# orck, au.cordoors.dev

ciAppType: MER

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1

I'm willing to accept that I'm a total idiot, and that the proxycache is
woefully misconfigured...
