dynamic config replication
by Gerard Ranke
Hello list,
Openldap 2.4.45 here, on 1 producer and 4 consumers. ( I'll attach
relevant parts of the configuration at the end of this message. )
Following the scripts from test059, I configured the producer to serve
up a cn=config backend for the consumers. This seems to work nicely at
first: When you start a consumer from a minimal config, it loads the
producers schemafiles and the cn=config, and replication of the main
database is fine. Also, when fi. changing the loglevel on the producers
cn=config,cn=slave, the consumers pick up this change in their cn=config.
However, when I modify an olcAccess line on the producers
cn=config,cn=slave database, I get these errors on the consumer:
slapd[26324]: syncrepl_message_to_entry: rid=002 DN:
olcDatabase={1}mdb,cn=config,cn=slave, UUID:

This is identical to the consumers olcDatabase={0}config,cn=config entry.
Hopefully somebody can point me in the right direction!

Acl on a replicated tree: unable to bind as user
by Giuseppe Civitella
Hi all,
I've got a master / slave replica setup. I did use this tutorial to set
up the replica:
https://wiki.debian.org/LDAP/OpenLDAPSetup
My ldap tree is something like: Root -> o=(first level local branch),
o=(first level replicated branch).
The local branch is just a cut and paste of the replicated branch.
On the slave server I can use the replicated branch to authenticate
against a Radius server.
On the master server I realized I cannot let web users authenticate
against the replicated branch.
If I try to bind as a user from the replicated branch, on both the
master and the slave, I get:
ldapwhoami -H ldap://localhost -D
"uid=gcivitella,ou=users,o=isiline,dc=who,dc=is" -W
Enter LDAP Password:
ldap_bind: Invalid credentials (49)
On the master, on the local branch, I get:
ldapwhoami -H ldap://localhost -D
"cn=gcivitella,ou=users,o=area51,dc=who,dc=is" -W
Enter LDAP Password:
dn:cn=gcivitella,ou=users,o=area51,dc=who,dc=is
I did try to configure the acl on the server to disallow anonymous bind.
And, once found this problem, I did try to create a bind user
(uid=read_only) able to read the replicated branch, userPassword attrs
included.
Unfortunately this did not solve the problem.
My acl on the master are:
dn: olcDatabase={1}mdb
objectClass: olcDatabaseConfig
objectClass: olcMdbConfig
olcDatabase: {1}mdb
olcDbDirectory: /var/lib/ldap
olcSuffix: dc=who,dc=is
olcAccess: {0}to dn.subtree="o=isiline,dc=who,dc=is" by dn="uid=read_only,ou
=binds,dc=who,dc=is" read
olcAccess: {1}to dn.subtree="o=isiline,dc=who,dc=is" by dn="uid=isi_replica,
ou=binds,dc=who,dc=is" read
olcAccess: {2}to attrs=userPassword by self write by anonymous auth by * non
e
olcAccess: {3}to attrs=shadowLastChange by self write by * read
olcAccess: {4}to * by users read
I'm quite new to this kind of setup, is this something to be expected?
Is there a way to bind directly on the replicated branch?
Regards,
Giuseppe

The accesslog should never write an operation that can't be replicated. If
the MOD is a valid LDAP operation (which I think it is), then it should be
accepted at the frontend. The issue may be more in delta-syncrepl's
handling of the write op than anything else.

consumer abort with chain overlay
by Michael Wandel
hallo ,
i'm not sure if I it is a configuration failure or a openldap error.
I have tested this with centos 7 , original RPM, SLES12SP3 and the
ltb-project binäries. Every enviroment failed.
this is a setup consumer / provider with chain overlay and proxyauth.
a minimized slapd.conf global section
...
authz-policy to
overlay chain
chain-uri "ldap://ldap1.example.test"
chain-rebind-as-user FALSE
chain-idassert-bind bindmethod="simple"
binddn="cn=chainadmin,dc=example,dc=test"
credentials="secret"
mode=legacy
flags=override
chain-return-error TRUE
...
the java code snipplet which makes a connection and then switch the
proxyauth and make a password change.

contextCSN not found on consumer!
by Sam Culley
I have recently set up a provider/consumer using OpenLDAP 2.4.40,
everything appears to be working. Changes made on the provider are
replicated to the consumer but when querying the contextCSN I am only able
to retrieve results for the provider.
[root@prod-mail-ldap-master ~]# ldapsearch -z1 -LLLQY EXTERNAL -H ldapi:///
-s base -b dc=domain,dc=cp, contextCSN
dn: dc=domain,dc=com
contextCSN: 20180222075803.816626Z#000000#000#000000
[root@prod-mail-ldap-slave-1 ~]# ldapsearch -z1 -LLLQY EXTERNAL -H
ldapi:/// -s base -b dc=domain,dc=cp, contextCSN
dn: dc=domain,dc=com
As you can see from the command outputs above when running the same
commands on both provider/consumer only the provider returns the contextCSN.
Why is this happening, what do I need to do to retrieve the contextCSN from
the consumer?

Sam

Hum primaryGroup is not an LDAP field so I don’t think you can use it like that. You can use %gidNumber% but I’m not sure it will help.
You can open an issue to make the primary group name available as %primaryGroup% in templates but I can’t guarantee it will be added.

Even just fetching the day of today does not work under unix Password Expiration data:
The epoch modifier was added in FusionDirectory 1.2.1 which is not out yet.

My users are allowed to change some info on their own but non of them find the edit button since it’s in the bottom right corner where nobody looks.

You can create you own CSS theme in which you can change the button display. See https://fusiondirectory-developer-documentation.readthedocs.io/en/latest/...

The rsyslog plugin was removed some versions ago.

If what you want is to track what users are doing inside FD, you can use the audit plugin.
