Problem with "force user to password reset at first login
by Rajagopal Rc
Hi,
I am trying to force users to change their password at first login or
after
password reset by administrator.
Tried following:
1)Password policy 'pwdMustChange TRUE' doesn't seems to be working as non
of the
users get prompt to change their password at first login.
2) used the 'pwdReset TRUE' attribute in users attributes, and it won't
prompt
to change the password and didn't allow to login
i observe below messages in log
"slapd[12684]: connection restricted to password changing only
slapd[12684]: send_ldap_result: err=50 matched="" text="Operations are
restricted to bind/unbind/abandon/StartTLS/modify password"
slapd[12684]: conn=1053 op=1 SEARCH RESULT tag=101 err=50 nentries=0
text=Operations are restricted to bind/unbind/abandon/StartTLS/modify
password"
Please help me configure the option to force all users to change their
password
at first login or after pwd reset by administrator.
Thanks & Regards
Raj

Error when try modify olcTLS*
by Igor Sousa
Hi everyone,
I've tried a common proceeded: insert CA and server certificates on
cn=config. I've created CA and server certificate in PEM format and I've
signed server certificate with CA certificate. Then I've created a
5tls.ldif with following content:
dn: cn=config
changetype: modify
replace: olcTLSCertificateFile
olcTLSCertificateFile: /etc/openldap/certs/ldap.local.crt
-
replace: olcTLSCertificateKeyFile
olcTLSCertificateKeyFile: /etc/openldap/certs/ldap.local.key
-
add: olcTLSCACertificateFile
olcTLSCACertificateFile: /etc/openldap/certs/ca.cert.pem
But server has returned following error when I've ran ldapmodify -Y
EXTERNAL -H ldapi:/// -f 5tls.ldif:
[root@localhost ldifs]# ldapmodify -Y EXTERNAL -H ldapi:/// -f 5tls.ldif
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
modifying entry "cn=config"
ldap_modify: Other (e.g., implementation specific) error (80)
ldap.local.crt, ldap.local.key and ca.cert.pem are /etc/openldap/certs and
they own read permission to ldap group.
I don't understand this behavior and I have no idea what is wrong.
OBS: I've mounted environment on CentOS 7, added symas' repository and
install from yum.
Here some relevant info below.

Cluster takes around 48 hours to synchronize after deletion
by x0101
Dear all,
We have an OpenLDAP 2.4 cluster of three nodes configured in multi-master and accessed through a VIP in round-robin. The three machines run RHEL7.
We noticed that deletion of an entry (done from a Windows machine onto the first node via Oracle's tool ldapmodify.exe) takes a long time (about 48 hours) to be replicated in the cluster.
Here's the relevant extract of cn=config for the first node:
olcSyncrepl: {0}rid=001 provider=ldap://mynode2:389/ bindmethod=simple
binddn="cn=Replicator,dc=mydomain,dc=org" credentials=1234567890 searchbase="dc=mydomain,dc=org" scope=sub schemachecking=on type=refreshAndPersist
retry="30 5 300 +" keepalive="60:5:10"
olcSyncrepl: {1}rid=002 provider=ldap://mynode3:389/ bindmethod=simple
binddn="cn=Replicator,dc=mydomain,dc=org" credentials=1234567890 searchbase="dc=mydomain,dc=org" scope=sub schemachecking=on type=refreshAndPersist
retry="30 5 300 +" keepalive="60:5:10"
olcMirrorMode: TRUE
We looked up for the offending entry (thisentry) in all nodes' logs and we found this line on mynode3:
Jun 18 14:18:20 mynode3 slapd[8871]: conn=1987936 op=14 DEL dn="dc=thisentry,ou=myou,ou=foobars,dc=mydomain,dc=org"
There are no other references to thisentry (apart from SRCH operations) on node1 and node2, even if the entry was originally deleted from node1, as said above.
What could be the cause and what could we do to further troubleshoot the issue? Thanks in advance.

Invalid DN reported during authentication
by Chris K
Hello experts,
I setup an openLDAP server some time ago and am to create a newer server
for TLS 1.3 support.
I am using a fully patched CentOS 7 server with OpenLDAP 2.4.44 and am
seeing 'invalid DN' when authenticating to the server from my Linux client.
I will attempt to supply all the config and tests I have done thus far:

Hide pwdHistory field from anonymous

I am able to hide the userPassword and any other single/unique fields on a query, but I cannot figure out the pwdHistory and how to disable it from anonymous queries. I keep getting syntax errors and am unsure what the syntax is.

How to filter all entries by multi-value attributes?
by Tankman 六四
Hi everyone
Is there a way to find all people whose telephoneNumber is
multi-valued through the use of LDAP filter?
Searched around there are only ways to search into multiple values but
not based on the number of values.
Thanks:)

LDAP with TLS Enable/Disable not working
by Sunkad, Abhilash
Hi All,
I am facing a strange problem. I am using FreeRadius 3.16 version for my Proxy authentication.
I have an AD server and I make an authentication request enabling TLS. So the TLS connection passes and authentication is successful.
Now I have one more LDAP server where its non TLS. Now if I make a call, even though TLS is disabled on this server, Client tries to make a TLS connection and fails. I have tried freeing connections but with no luck. Please help.
Thanks

Yeah this is what I was calling timestamp sorry, getting the integer for today is easy, but it seems there is no way for writing a search filter with greater-than or lesser-than for this attribute.
It has to do with the LDAP protocol that LDAP lets schema define attributes in ways that forbid substring and range filters. We should be able to use extensible filters for these, and specify which ordering or substring rule we want to see used.
And if attributes using integer syntax were to default to integerOrdering when not specified, that would seem more sane.

Extensible filters and substring searches
by Côme Chilliet
Hello,
I’m trying to understand if it is possible or not to do a substring search on an attribute which does not specify a substring matching rule.
I was expecting to be able to use an extensible filter and specify the sub matching rule to use, but it does not seem to work ldapsearch says "ldap_search_ext: Bad search filter (-7)" as soon as the filter contains an asterisk.
And indeed reading https://tools.ietf.org/html/rfc4515 it does look like extensible filter does not allow asterisk, but it is surprising to me.
Is there really no way to do an extensible search on a substring?
I found some examples on the web of such filters, like here: http://www.zytrax.com/books/ldap/apa/search.html
They give these examples:
> # override SUBSTR match with case sensitive match
> sn:caseExactSubstringMatch:=*S* # only finds Smith
> # functionally same as above using OID
> sn:2.5.13.7:=*S*
But these do not work if I try them in ldapsearch I get bad search filter.
