slapd cannot work on FreeBSD 5.2.1 sparc64:

sparc64# ldapsearch -x -b "dc=komi,dc=mts,dc=ru"
ldap_bind: Authentication method not supported (7)
        additional info: unknown authentication method

log:

but ldapsearch works fine with i386 OpenLDAP server:

sparc64# ldapsearch -x -b "dc=komi,dc=mts,dc=ru" -h i386 -LLL '(uid=bill)' uid
dn:: Y249Q0JPU1MgYmlsbGluZyxvdT3QodC70YPQttCx0LAg0YDQsNGB0YfQtdGC0L7QsixvdT1Nb

uid: bill

slapd.conf:

include         /usr/local/etc/openldap/schema/core.schema

I got this error on two configurations: 

1. OpenLDAP 2.2.7 with Cyrus Sasl 2.1.18
2. OpenLDAP 2.2.7 without Cyrus Sasl

Thanks!
