Re: Fail to write in slave during replication



Your replication problem I feel you have an ACL problem.  userPassword is often governed by it's own ACL in the .access.conf file.   Make sure your replication user will use that ACL.  Also, check priority in ACLs.  There is an order in which they are applied.  It's documented in the manual pages and in the Admin guides online.


Your referral update problem is related the above problem.  You can never update a slave, and since the replication can not update the slave, you will never get a userPassword attribute.   Fix the replication first, and then regroup and attack the second problem.

Turn your LDAP logging up too and you should see the error more explicitly.

Dear all,
 
I set up my replication using syncrepl in 2.3.38. The setting is
 
slave
*****************************************************************
syncrepl rid=123
                provider=ldap://master:389
                type=refreshOnly
                interval=00:00:00:20
                searchbase="dc=mycompany,dc=com"
                schemachecking=on
                updatedn="uid=repl_writer,dc=mycompany,dc=com"
                bindmethod=simple
                binddn="uid=repl_reader,dc=mycompany,dc=com"
                credentials=secret
 
updateref  ldap://master:389
 
access to *
  by dn.exact="uid=repl_writer,dc=mycompany,dc=com" write 
        by dn.exact="uid=repl_reader,dc=mycompany,dc=com" read
****************************************************************
 
 
master:
****************************************************************
overlay         syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 100
 
access to *
  by dn.exact="uid=repl_writer,dc=mycompany,dc=com" write 
        by dn.exact="uid=repl_reader,dc=mycompany,dc=com" read
****************************************************************
 
 
Problem 1:
When I add following user in master:
****************************************************************
dn: uid=testuser,dc=mycompany,dc=com
objectclass: inetorgperson
uid: testuser
cn: cn
sn: sn
userpassword: secret
****************************************************************
 
The userpassword does not replicate to slave. The following is the replicated result in slave.
****************************************************************
# testuser, mycompany.com
dn: uid=testuser,dc=mycompany,dc=com
objectClass: inetOrgPerson
uid: testuser
cn: cn
sn: sn
****************************************************************
 
 
 
Problem 2:
Since the userpassword is missing in the entry, I want to add it in slave by manual.
    ldapmodify   -x   -D "cn=admin,dc=mycompany,dc=com" -w secret -f  /tmp/userpassword.ldif
 
The /tmp/userpassword.ldif is
****************************************************************
dn: uid=testuser,dc=mycompany,dc=com
changetype: modify
add: userPassword
userPassword:  NewSecret
****************************************************************
 
The following is the running result:
****************************************************************
modifying entry "uid=testuser,dc=mycompany,dc=com"
ldapmodify: Referral (10)
        referrals:
                ldap://master:389/uid=testuser,dc=mycompany,dc=com
 ****************************************************************

Even though the result shows that it will update master by referral,  the userpassword in master does not change, and the testuser in slave still do not have attribute userpassword.

After studying the replication configuration, and trying to search the mailist archive, I still do not know how to solve the problem.
 
Thank you.
 
Best regards,
Jacky
