secure passwords
by sim123 14 Sep '11

14 Sep '11

Hi All, I am trying to store SSHA passwords in openldap instead of plain text via C code and wondering how this works. I tried exploring archives, FAQ etc and what I gathered from there is openLDAP has built in support for various password encryption algorithm however it does not have any APIs for generating passwords and password-has directive works with ldpapassword utility only. http://www.openldap.org/faq/data/cache/906.html If I use some tool like Apache DS and modify my userPassword attribute to be SSHA instead of plain text it all works. I want to know how this works under the hood? Who is responsible for generating hashed passwords? If I generate it using some C routine how does LDAP Server retrieves it during the bind operation? I would really appreciate if there is any related documentation available. Thanks for the help and support.

Hi, ldapsearch -x shows the content of LDAP database as well wothout any additional options. I can see the same in one of my servers,I took a dump of the running server by slapcat and restored the same in this server. I can see the data by slapcat but ldapsearch is not working. The box where ldap running fine its using slapd.d backend, but this server i have configured to run from slapd.conf file, can it be a issue with the DB backup and restore as they are both using different backend?

Bind with attribute + RDN instead of DN
by sim123 13 Sep '11

13 Sep '11

Hi All, I want third party applications to authenticate against my ldap using any attribute (specially mail & password) is it possible to do a bind using any attribute with/without RDN rather then DN? For example my LDAP user looks like this : dn: uid=1,ou=users,dc=example,dc=local objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top cn: Josh sn: Cho mail: joshcho(a)example.com uid: 1 userPassword: joshcho I can bind to ldap if I use DN & password but I can not bind to ldap if I use any attribute like mail=joshcho(a)example.com,ou=users,dc=example,dc,local & password Would greatly appreciate any help. Thanks *simon*

Problem replicating ACL changes in back-config from master to slaves: SEGFAULT
by Uwe Werler 13 Sep '11

13 Sep '11

Hello list, I created a ldap master serving a ldif-db cn=config,cn=server for a bunch of slave servers replicating their config with suffixmassage cn=config. The master is 2.4.25 and the slaves are 2.4.25 and 2.4.26. If I change ACL's in the db definition of a bdb database at the master db cn=config,cn=server all slave servers segfault with: Error: closing the transaction region with active transactions slapd daemon: abnormal condition, shutdown initiated. slapd shutdown: waiting for 2 operations/tasks to finish Segmentation fault Any hint? Regards Uwe

Re: Need Help On Master-Master Replication Setup!!

Hi, Thanks for the suggestion, but i never did it before , if you can share a doc or something would be great. I use the openssl to generate the certificate, so even i dont know how to configure subjectAltNames. Also if you can explain a bit how i should i proceed would be appreciated. Example : ldap1.example.com ldap2.example.com So in the load balancer what to configure and how to create the certificate. Please help.

OpenLDAP Windows setup
by Ashish Chawla 12 Sep '11

12 Sep '11

Hi, I installed OpenLDAP on windows XP by running the application installer. I am new to OpenLDAP and facing lots of issues while running client tools. Am not able to add new users or run utilities like slapcat.exe- it gives error: " slapcat: database doesn't support necessary operations". Can somebody tell me a quick way of adding users and organizations and also if there is a way of capturing the detailed errors. I know that I can get help from this forum only. Any help in this regard will be of great use to me.

Re: Change a user dn
by Juan Diego Calle 12 Sep '11

12 Sep '11

Ok, let me rephrase this, I have read many books, like O'reilly s LDAP system administratoro, or docs like Or http://tools.ietf.org/html/rfc4511#section-4.9, that explains this exactly The Modify DN operation allows a client to change the Relative Distinguished Name (RDN) of an entry in the Directory and/or to move a subtree of entries to a new location in the Directory. The Modify DN Request is defined as follows: ModifyDNRequest ::= [APPLICATION 12] SEQUENCE { entry LDAPDN, newrdn RelativeLDAPDN, deleteoldrdn BOOLEAN, newSuperior [0] LDAPDN OPTIONAL } Fields of the Modify DN Request are: - entry: the name of the entry to be changed. This entry may or may not have subordinate entries. - newrdn: the new RDN of the entry. The value of the old RDN is supplied when moving the entry to a new superior without changing its RDN. Attribute values of the new RDN not matching any attribute value of the entry are added to the entry, and an appropriate error is returned if this fails. I read the paragraph above, and it seems pretty straight forward, I believe I understand how it works, but when I try to apply this to what I need I dont know what to do. I can change the UID, or other fields from the users or groups, but i can change the dn. For me Openldap has being really hard to understand, it is really technical, usually i am really good at this stuff. I am pretty sure I have huge gaps of knowledge that requires more reading, and a better understanding of the standards. But that is why I usually ask here when I am stuck. This is usually the last place I resort when I dont have answers.

Change a user dn
by Juan Diego Calle 12 Sep '11

12 Sep '11

Hi I have Openldap with samba, and some users. My users are part of ou=People,dc=mydomain,dc=com, like this, dn: uid=user1,ou=People,dc=mydomain,dc=com, So i wanted some of my users to be able to administer a group of users and be able to create users, so a friend of mine recommended me to do the following, create a group like this dn: cn=Admin Group1,cn=Admins,ou=People,dc=mydomain,dc=com, objectClass: groupOfNames objectClass: top cn: Admin Group1 member: uid=adming1,ou=People,dc=mydomain,dc=com, and dn: ou=Group1,ou=People,dc=mydomain,dc=com objectClass: organizationalUnit objectClass: top ou: U.A.A. Group1 the users of this "group" whould have to be dn: uid=user1,ou=Group1,ou=People,dc=mydomain,dc=com, And with and acl I give Admin Group1 users complete control over that ou. So this seems to work. But I already have users that use my ldap, is it possible to change their dn, I am not clear on how to do this. Thanks, Juan Diego
