I have simply

TLSCACertificateFile /etc/pki/tls/certs/ca-bundle.crt
TLSCertificateFile /etc/pki/tls/certs/ldap.icpsr.umich.edu.crt
TLSCertificateKeyFile /etc/pki/tls/private/ldap.icpsr.umich.edu.key


in my slapd.conf.    CACertificateFile is almost certainly not required for a server cert.


Maybe you are running into an oddity of the cn=config?  Have you tried just opening up the permissions to make sure the files are world readable?  no selinux involved?



Folks on the list will probably yell at you to use the current version rather than the centos packages. 

If you look through the archives for the last few weeks, you will find a pointer to a site that has rpm builds of current openldap.

Hey ldap folks!

I've attempted to add TLS capabilities to my newly created LDAP server using the following document: 

http://www.server-world.info/en/note?os=CentOS_6&p=ldap&f=3

This is how my cert files are looking in terms of ownership and permissions:

[root@puppet:~] #ls -l /etc/pki/tls/*/* | grep ldap

-r-------- 1 ldap root   1241 Feb 19 13:06 /etc/pki/tls/certs/ldap.crt

-r-------- 1 ldap root   1021 Feb 19 13:05 /etc/pki/tls/misc/ldap.csr

-r-------- 1 ldap root   1679 Feb 19 13:01 /etc/pki/tls/private/ldap.key

I got to the point where I'm attempting to add the configuration parameters to my ldap setup like so:

[root@puppet:~] #ldapmodify -Y EXTERNAL -H ldapi:///

SASL/EXTERNAL authentication started

SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth

SASL SSF: 0

dn: cn=config

add: olcTLSCertificateFile

olcTLSCertificateFile: /etc/pki/tls/certs/ldap.crt

-

add: olcTLSCertificateKeyFile

olcTLSCertificateKeyFile: /etc/pki/tls/private/ldap.key

modifying entry "cn=config"

ldap_modify: Inappropriate matching (18)

        additional info: modify/add: olcTLSCertificateFile: no equality matching rule

These are the package version numbers I have installed via yum on CentOS 6.5:

openldap-2.4.23-34.el6_5.1.x86_64

openldap-devel-2.4.23-34.el6_5.1.x86_64

openldap-servers-2.4.23-34.el6_5.1.x86_64

openldap-clients-2.4.23-34.el6_5.1.x86_64

Can anyone offer some wisdom as to why this error is happening? Or perhaps offer some better documentation on how to enable the TLS abilities of openldap?

Thanks

Tim
