test050-syncrepl-multiprovider failed for mdb

The part of the test script which is failing is:

echo "Adding schema and databases on server 1..." $LDAPADD -D cn=config -H $URI1 -y $CONFIGPWF <<EOF >>$TESTOUT 2>&1 include: file://$ABS_SCHEMADIR/core.ldif

include: file://$ABS_SCHEMADIR/cosine.ldif

include: file://$ABS_SCHEMADIR/inetorgperson.ldif

include: file://$ABS_SCHEMADIR/openldap.ldif

include: file://$ABS_SCHEMADIR/nis.ldif EOF RC=$? if test $RC != 0 ; then echo "ldapadd failed for schema config ($RC)!" test $KILLSERVERS != no && kill -HUP $KILLPIDS exit $RC fi

Notes on script. - KILLSERVERS : unset. set to "no" to keep servers alive. - LDAPADD : comes from tests/scripts/defines.sh LDAPADD="$CLIENTDIR/ldapmodify -a $TOOLPROTO $TOOLARGS" - TESTOUT : also from defines.sh ./build/sparcv7/tests/testrun/test.out
