rewriteContext bindDN not work in slapd-relay.
It shows 'Invalid credentials' all the time.
And a strange error appears, such as
bdb_dn2entry("uid=test_ooyama,ou=auth1,dc=hasiru,dc=net")
=> bdb_dn2id(",ou=auth1,dc=hasiru,dc=net")
<= bdb_dn2id: get failed: DB_NOTFOUND: No matching key/data pair found (-30990)
My rewrite rule is
rewriteContext  bindDN
rewriteRule "^(.+,)ou=samba1,dc=hasiru,dc=net$"
            "$1ou=auth1,dc=hasiru,dc=net"
            ":"
