Using the following rwm configuration:

overlay rwm
rwm-rewriteEngine on

rwm-rewriteContext searchFilter
rwm-rewriteRule "(.*)" "(&(ou=openldap)$1)" ":@I"

1.) works fine after starting slapd with: slapd -f slapd.conf
2.) converts fine (at least no error messages): slaptest -f slapd.conf -F
slapd.d
3.) but slapd's startup aborts when using: slapd -F slapd.d


fyi here's slapd's output when started "slapd -F slapd.d -d -1" (rwm-related
output):

==> here the shell is back :-/


BTW: after commenting out 'rwm-rewriteRule "(.*)" "(&(ou=openldap)$1)" ":@I"'
slapd starts just fine. Adding this rule vi cn=config works, but
searchfilter-rewriting does not work. Removeing the rule via cn=config results
in assertion error rwm.c's function "rwm_cf_gen" in line 2158.
