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

role based authorization -> dynacl module?
by Daniel Tröder
Hello everyone,
I am in the process of implementing a role concept via ACLs and hope for
a hint so that I don't invent the wheel a second time.
Specifically, it is about identity management for schools. A user
(object) can have several roles in multiple schools. Permissions on
other LDAP objects can thus differ depending on the role(s) the user and
the object have in the same school(s).
For example, a user could have been assigned the following roles that
are scattered over several schools:
→ "Teacher" in school 1
→ "School admin" in school 2
→ "Parent" in school 3
→ both "Teacher" and "Staff" in school 4
ACLs should now be defined accordingly, e.g.
→ the role "teacher" at school X can reset the password for the role
"student" at school X
→ the role "teacher" at school X *cannot* reset the password for the
role "student" of school Y
→ the role "school administrator" at school X can reset the password for
the roles "student" and "teacher" at school X
→ ...
So far I have not seen any way to map such a construct via groups or
sets without including a separate ACL for each group, which is a
performance issue.
Is there another way to map the role concept besides implementing an own
dynacl module?
Greetings,
Daniel

issues with equality matching and slapd death
by Christopher Paul
Hello Fellow OpenLDAP Techs,
I'm having an issue with equality matching and slapd death (just another
day in the life of an LDAP guy...).
version info:
OpenLDAP: slapd 2.4.44
Red Hat Enterprise Linux Server release 7.5 (Maipo)
RH package: openldap-servers-2.4.44-15.el7_5.x86_64
While planning for a migration, I ran into the following error:
$ ldapmodify -x -y ~/.ldappw
dn: uid=cs5555,ou=testPrimary,ou=mailhosts,dc=test,dc=com
changetype: modify
add: mailAlternateAddress
mailAlternateAddress: cs5555(a)test.com
[CTRL-D]
modifying entry "uid=cs5555,ou=testPrimary,ou=mailhosts,dc=test,dc=com"
ldap_modify: Inappropriate matching (18)
additional info: modify/add: mailAlternateAddress: no equality
matching rule
I tried to fix this by updating the schema to add "EQUALITY
caseIgnoreMatch" to the attribute definition for mailAlternateAddress.
dn: cn={5}inetLocalMailRecipient,cn=schema,cn=config
objectClass: olcSchemaConfig
cn: {5}inetLocalMailRecipient
olcAttributeTypes: {0}( 2.16.840.1.113730.3.1.24 NAME

'inetLocalMailRecipient' D
ESC 'iPlanet defined objectclass' AUXILIARY MAY ( mailAlternateAddress
$ mail
Host $ mailRoutingAddress ) X-ORIGIN 'iPlanet Messaging Server' )
Now, after the schema change, the same ldapmodify kills slapd.
$ ldapmodify -x -y ~/.ldappw
dn: uid=cs5555,ou=testPrimary,ou=mailhosts,dc=test,dc=com
changetype: modify
add: mailAlternateAddress
mailAlternateAddress: cs5555(a)test.com
modifying entry "uid=cs5555,ou=testPrimary,ou=mailhosts,dc=test,dc=com"
ldap_result: Can't contact LDAP server (-1)
Trying this with slapd running with olcLogLevel=-1, I get the following
output before slapd death:

Does the same apply to the rfc2307bis schema which gives your the

olcTLSCACertificateFile and olcTLSCertificateFile displayed as encrypted?
by Jean-Francois Malouin
Hi,
Not a very important question, just a little puzzled by this...
Is there a reason why the olcTLSCACertificateFile and olcTLSCertificateFile
paths show up as encrypted in this cn=config search?
slapd 2.4.46 on Debian 9.5 (Stretch)
ldapsearch -LLLQY EXTERNAL -H ldapi:/// -b 'cn=config' -s base
dn: cn=config
objectClass: olcGlobal
cn: config
olcArgsFile: /var/run/slapd/slapd.args
olcLogLevel: stats
olcLogLevel: sync
olcPidFile: /var/run/slapd/slapd.pid
olcServerID: 1
olcTLSCACertificateFile:: IC9ldGMvbGRhcC9zc2wvQ09NT0RPX0NBX2J1bmRsZS5jcnQ=
olcTLSCertificateFile:: ICAgL2V0Yy9sZGFwL3NzbC9TVEFSX2JpY19tbmlfbWNnaWxsX2NhLmNydA==
olcTLSCertificateKeyFile: /etc/ldap/ssl/STAR_bic_mni_mcgill_ca.key
olcTLSCipherSuite: NORMAL
olcTLSVerifyClient: allow
olcToolThreads: 1
There is an extra ':' ...
When I edit/display the cn=config with ldapvi (old fart here!) they show up as:
olcTLSCACertificateFile:; /etc/ldap/ssl/COMODO_CA_bundle.crt
olcTLSCertificateFile:; /etc/ldap/ssl/STAR_bic_mni_mcgill_ca.crt
again, notice the ';' this time...
Just curious!
Thanks,

slapo-memberof and Replication
by Meike Stone
Hello,
I need the memberof Attribute on users, and I configured it with the
memberof overlay. Every thing ist working fine. I like to deploy a
second server for redundancy reason., but the manual page of the
overlay says:
" .. Replica servers should be configured with their
own instances of the memberOf overlay if it is desired to maintain
these memberOf attributes on the replicas. Note that slapo-memberOf
is not compatible with syncrepl based replication, and should not be
used in a replicated environment. ..."
That confuses me a little bit.
All replication on openLDAP are based on syncreplication (slurpd is
vanished a long time ago)
So what kind of replication means the manual page (-> "Replica servers")?
Thanks Meike

SASL EXTERNAL olcRootDN and ACLs
by linux nuse
https://www.openldap.org/doc/admin24/access-control.html says:
Regardless of what access control policy is defined, the rootdn is always allowed full rights (i.e. auth, search, compare, read and write) on everything and anything.
As a consequence, it's useless (and results in a performance penalty) to explicitly list the rootdn among the <by> clauses.
"Well", said I and set olcRootDN to gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth.
Then I've tried to add an entry with
$ sudo ldapadd -Y EXTERNAL -H ldapi:/// ....
and OpenLDAP told that I don't have permission to modify the DB.
I had to grant gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth access to everything in the backend's ACL to make it working.
Is it expected that gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth rootdn does not have full rights without explicit permission or I need to recheck because I could get something wrong (didn't restart slapd or something like that)?

Thanks - You too.
In my case, the present-phase is not really useful, since this particulat ldap-instance only ever adds and modifies entries, never deletes. Would it then be possible to skip it ?

Slapd generate SQL by PostgreSQL based syntax

Hi
I use openldap slapd 2.4.40 + MySQL5.5 as back-sql on CentoS 6.9
It seems slapd generate PostgreSQL based syntax SQL
Here is the error message for ldapsearch -x -b "dc=example,dc=com"

I take same message as I execute below from MySQL console.
I can see text('inetOrgPerson') in the SQL which was generated by slapd
however,MySQL doesn’t support text() function in its SQL.
When I use Postgeresql as back-sql it works properly
Is it a bug or setting error for some directives?

How to make ldap evaluate clear text password vs DES stored password
by yokoyamy＠jacic.or.jp
Hi.
I have user information in RDB which include user-id and password set.
I’ve been trying to use this RDB as backend database for openldap server.
Now,I can find user information in RDB through openldap.
However, I recognized I can’t use this user information for ldap login certification process.
LDAP’s userPassowrd stored in the RDB has been already DES hashed by original app. On the other hand, input password from ldapseach command line is CREARTEXT.
Now I’d like my openldap to change CREATEXT input password into DES hassed text so that they'll match for certification.
I've asked this topic on stackoverflow web site how to do that by server settings.But I couldn’t find proper directives to set.
How to make ldap evaluate clear text password vs DES stored password
Since then,I’ve been searching LDAP source files which is matching input password from ldapsearch command line against userPassword stored in backend RDB for slapd.
I’d like to change certification process of LDAP source file to make input password into DES hashed by using 2 characters of userPassword as its SALT.
I've already known that 2 characters at the beginning of userPasswordwas used as its SALT when it was hashed.
So the fact is ,my slapd can read userPassword from the RDB. I think I'll be able to find out what will be SALT to make input password into DES hashed text.
If I can make opeldap to act this way,I can use user's infomation in the RDB to ldap login inforomation wiht seamless.
