Please note that all double quote characters in this example are plain ASCII characters not typographical ones!

Step 1: first we need to install the required packages:

#yum install openldap-servers migrationtools

Step2: As the configuration for LDAP is stored inside the LDAP server itself the configuration has to be done by editing LDIF files under the /etc/openldap/slapd.d/ directory.

Now create the ldap password:

#slappasswd

youll get something like this {SSHA}r2or9f2vYlvieCu0LP6wTnSdYfrddsuV as a result. This is the string we will have to add to the bdb.ldif config file.

# vim /etc/openldap/slapd.d/cn=config/olcDatabase={1}bdb.ldif

substitute my-domain.com with yourdomain.com

:%s/dc=my-domain,dc=com/dc=yourdmain,dc=com/g

Step 3: We now set the admin password and specify the location of our encryption certificate and key.

add these 3 lines at the end of the file bdb.ldif file:

olcRootPW: {SSHA}r2or9f2vYlvieCu0LP6wTnSdYfrddsuVolcTLSCertificateFile: /etc/pki/tls/certs/slapdcert.pemolcTLSCertificateKeyFile: /etc/pki/tls/certs/slapdkey.pem

Step 4: Now we have to specify the monitoring privileges

#vim /etc/openldap/slapd.d/cn=config/olcDatabase={2}monitor.ldif

again, we have to replace the default domain name with our domain name

:%s/cn=manager,dc=my-domain,dc=com/cn=Manager,dc=yourdomain,dc=com/g

Step 5: Now its time for the Database Cache

#updatedb

#cp /usr/share/doc/openldap-servers-2.4.19/ DB_CONFIG.example /var/lib/ldap/DB_CONFIG

#chown -Rf ldap:ldap /var/lib/ldap/

Step 6: Now we will need to set up a certificate for TLS. First we need to edit /etc/sysconfig/ldap and change SLAPD_LDAPS from no to yes.

#vi /etc/sysconfig/ldapSLAPD_LDAPS=yes

Now we can create the certificate

#openssl req -new -x509 -nodes -out /etc/pki/tls/certs/slapdcert.pem -keyout /etc/pki/tls/certs/slapdkey.pem -days 365

This will create the two required keys in the /etc/pki/tls/certs/ directory. We need to make them readable for the ldap user.

# chown -Rf root:ldap /etc/pki/tls/certs/$cert.pem# chmod -Rf 750 /etc/pki/tls/certs/$key.pem

Step 7: Time to test our configuration

# slaptest -uconfig file testing succeeded

Step 8: Start the ldap server

#service sladp start

lets check if our ldap server really works:

#ldapsearch -x -b dc=yourdomain,dc=com

if you get a search: 2 then your on track!

Step 9: Configure the base domain

#vi base.ldif

dn: dc=yourdomain,dc=netdc: yourdomainobjectClass: topobjectClass: domain

dn: ou=People,dc=yourdomain,dc=netou: PeopleobjectClass: topobjectClass: organizationalUnit

dn: ou=Group,dc=yourdomain,dc=netou: GroupobjectClass: topobjectClass: organizationalUnit

now we import our base information to the ldap directory:

#ldapadd -x -W -D cn=Manager,dc=yourdomain,dc=com -f base.ldif

Step 10: lets migrate the users

Go to the directory /usr/share/migrationtools. Edit the file

# vim /usr/share/migrationtools/migrate_common.ph


3 of 39 8/26/2013 10:17 AM

Set:# Default DNS domain$DEFAULT_MAIL_DOMAIN = yourdomain.com;# Default base$DEFAULT_BASE = dc=yourdomain,dc=com;

#grep :5[0-9][0-9] /etc/passwd > passwd#grep :5[0-9][0-9] /etc/group > group#./migrate_passwd.pl passwd > users.ldif#./migrate_group.pl group > group.ldif#sed -e s/ou=Group/ou=Groups/g group.ldif > groups.ldifldapadd -x -W -D cn=Manager,dc=yourdomain,dc=com -f users.ldifldapadd -x -W -D cn=Manager,dc=yourdomain,dc=com -f groups.ldif

Step 11: Testing the ldap server. We check if user mani exists

#ldapsearch -x cn=mani -b dc=mycompany,dc=com

If the test is successful your done

Hey, this is a great posting. Thanks so much for taking the time to do this.

I do have one question though..

When I add: olcRootPW: {SSHA}. as part of your instructions

1.


4 of 39 8/26/2013 10:17 AM

I get the following message when I run the slaptest -uolcRootPW: value #0: can only be set when rootdn is under suffix

I cant see what Ive missed. If I comment that line out of the olcDatabase={2}monitor.ldif the error goes away, but I of course cant authenticate either.

Any ideas?

Reply

laurent says:April 6, 2011 at 10:24 pm

Yes the 3 lines

olcRootPW: {SSHA}r2or9f2vYlvieCu0LP6wTnSdYfrddsuVolcTLSCertificateFile: /etc/pki/tls/certs/slapdcert.pemolcTLSCertificateKeyFile: /etc/pki/tls/certs/slapdkey.pem

have to be added to the /etc/openldap/slapd.d/cn=config/olcDatabase={1}bdb.ldif file not the olcDatabase={2}monitor.ldif.

Hi, thanks for the help. Ive been looking for some help for a while. I stuck on a certain point. Where you import base information:ldapadd -x -W -D cn=Manager,dc=yourdomain,dc=com -f base.ldif

I get an error:Enter LDAP Password:ldap_bind: Invalid DN syntax (34)additional info: invalid DN

I dont know why Im getting this error. I changed yourdomain to example which is my domain.

Any help would be appreciated, thanks,Rob

Hi Robert,

You have to pay attention the syntax in the ldif file:

Here an example:dn: dc=domb,dc=net // (dn:[whitespace] dc=domb,dc=net [ENTER])dc: dombobjectClass: topobjectClass: domain [ENTER][ENTER]dn: ou=People,dc=domb,dc=netou: PeopleobjectClass: topobjectClass: organizationalUnit[ENTER][ENTER]dn: ou=Group,dc=domb,dc=netou: GroupobjectClass: topobjectClass: organizationalUnit

Hope this helps to solve your problem. If not post me your base.ldif

Thank you very much for the post, and all of the others here too! Im studying for the RHCE and although I have a good background with a lot of thematerial from working in webhosting for many years, LDAP is brand new to me and this was the simplest and most lucid tutorial Ive yet found.

I do have one suggestion, and it may help others too. Please change the double quote characters in your example to use the plain ASCII characterinstead of the typographical open and close quote characters. Like Robert above, the ldapadd command initially gave me this error

ldap_bind: Invalid DN syntax (34)additional info: invalid DN

It turned out to be the result of the UTF-8 open and clsoe quote chars. I had to change the command from this

ldapadd -x -W -D cn=Manager,dc=yourdomain,dc=com -f base.ldif

to this

ldapadd -x -W -D cn=Manager,dc=yourdomain,dc=com -f base.ldif

(And I hope WordPress doesnt auto change those quotes on me! The second line should have the non-curved typewriter double quote symbol from theASCII set.)

One add on to Laurents entry if you use a self-signed Certification. Remember to add below line as well to bdb.ldif:

Otherwise, running request with TLSldapsearch -x -b dc=yourdomain,dc=net -ZZyoull get Self-signed certificate error.

Excellent posting. I teach Linux at a local community college and after reading some of the postings I suspect some of the above users are coping andpasting your text into their config files. This changes the formatting and will give them errors; even the command dos2unix will not always fix this. Thereis one typo that may throw a newbie off: you have service sladp start Like me, you probably have large fingers. Thanks again fro supporting thecommunity.Kind regards,Randy

Thank you so much for an easy to follow guide.I have installed and configured openldap on my rhel6 server and would want to use FreeRadius with openldap. The two are working well separatley and Iwould now like to set them up such that users can connect through Freeradius and authenticate on an openldap backend. Can you point me todocumentation for doing this on rhel6?The documentation that i am currently getting refers to a different version and I have configuration files (unedited) that are completely different fromwhat I am referred to. I understand that RHEL has a different radius configuration file and I wold want to know how to configure freeradius to seopenldap for authentication.

Thank you for putting out this step by step guide. Without it, it is almost impossible to get openLDAP setup with RHEL6. You should considercontributing this piece to openldap project as there are many people who might be able to save time using this.
