Hi Dieter,
Thanks for your kindly replies.
In my case, I don't use any SASL. I want to use simple bind, but my mirror mode can't work when my rootpw in hash( if the rootpw is in cleartext , the mirror mode can work). Could you pls advice what is wrong with my configration?
My slapd.conf file set as below.
moduleload syncprov.la
database bdb
suffix "dc=xxx,dc=xxx"
checkpoint 1024 15
rootdn "cn=manager,dc=xxx,dc=xxx"
rootpw {SSHA}aeiyuikahdkfjhdiuvy
directory /var/lib/ldap/xxx
access to *
by self write
by * read
# Indices to maintain for this database
index objectClass,entryCSN,entryUUID eq,pres
index ou,cn,mail,surname,givenname eq,pres,sub
index uidNumber,gidNumber,loginShell eq,pres
index uid,memberUid eq,pres,sub
index nisMapName,nisMapEntry eq,pres,sub
serverID 1 (ldap2 service is 2)
syncrepl rid=001
provider=ldap://other side ip
bindmethod=simple
binddn="cn=manager,dc=xxx,dc=xxx"
credentials={SSHA} aeiyuikahdkfjhdiuvy
searchbase="dc=xxx,dc=xxx"
schemachecking=on
type=refreshAndPersist
retry="60 +"
mirrormode on
overlay syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 100
Thanks and regards

Hi,
If I remeber correctly, you mentioned sasl authentication. My comments on plaintext passwords are only related to sasl authentication. A sasl authentication is based on a SASL MECHANISM, as described in rfc-4422.
In order to compare the sasl authentication string with the stored password value, this has to be cleartext.
If your ldap operation is based on a simple bind, the stored password can, and should be, hashed.
