Re: Reg OpenLdap on Ubuntu

[Asimananda Mohanty <asimananda.mohanty@gmail.com>]

Hi Matt,

openldap user is already a part of ssl-cert group.

Regarding apparmor, I am very much new to this. But I did some research on this and did some changes like :

1. moving the /usr/sbin/slapd profile to complain mode and 
2. changing the following lines in /etc/apparmor.d/usr.sbin.slapd from :

/etc/ssl/private/ r,
/etc/ssl/private/* r,

to 

/etc/ssl/private/ mixr,
/etc/ssl/private/* mixr,

After the changes, I did the following :

/etc/init.d/apparmor stop
 update-rc.d -f apparmor remove

/etc/init.d/apparmor start
update-rc.d apparmor defaults

But it yields no positive result.

Is there anything else that I need to do?

Please let me know.

Thank you very much for the reply.

Make sure slapd can read the certs and private key.  In addition to typical ownership and permissions, the openldap user should belong to the ssl-cert group and the slapd AppArmor profile must allow access to the directories containing your certs.

Hi,

I ran the command "slapd -d 16383" and attached is the output of the same in case it may prove to be useful.

In this output, ldap-company.com.crt is server.crt as defined in in my earlier mails. I have changed it to try some luck, but it was fruitless.

Hi Matt,

I created the certificates following the procedure defined in https://help.ubuntu.com/8.10/serverguide/C/openldap-server.html

I created a CA and signed the certificate as defined the steps.

The ownership is of openldap:openldap for cacert.pem and server.crt and openldap:ssl-cert for server.key.

rwx permission is 644 for all the three.

Thanks for the reply.

How did you create the certificates?  Can slapd read them?

Hi All,

I am currently busy configuring OpenLdap on my newly installed Ubuntu 9.04.

Here is what I have done till now.

I followed the steps defined in https://help.ubuntu.com/8.10/serverguide/C/openldap-server.html and installation was successful. I installed PhpLdapAdmin also.

After I created certificate, key etc, I created a .ldif file (enable-ca.ldif) with the following content :

dn: cn=config
add: olcTLSCACertificateFile
olcTLSCACertificateFile: /etc/ssl/certs/cacert.pem
-
add: olcTLSCertificateFile
olcTLSCertificateFile: /etc/ssl/certs/server.crt
-
add: olcTLSCertificateKeyFile
olcTLSCertificateKeyFile: /etc/ssl/private/server.key

Then I executed the command :

ldapmodify -D "cn=admin,cn=config" -x -w 12345678 -f enable-ca.ldif

and it was a success.

But after this, when I tried to restart slapd, I got errors like the following :

main: TLS init def ctx failed: -1

I noticed that after I executed "ldapmodify -D "cn=admin,cn=config" -x -w 12345678 -f enable-ca.ldif", 3 lines are added to /etc/ldap/slapd.d/cn=config.ldif and when I commented the last two lines like the following,  slapd started successfully.

olcTLSCACertificateFile: /etc/ssl/certs/cacert.pem
#olcTLSCertificateFile: /etc/ssl/certs/server.crt
#olcTLSCertificateKeyFile: /etc/ssl/private/server.key

This looks quite strange.

Please help me resolving the same.
