Test LDAP Setup

These instructions are to setup the OpenNIC object schemas in slapd. This will only work on systems that use the cn=config type of configuration(not slapd.conf). It has been tested on Debian 8.

1) Install OpenLDAP (slapd)

Follow documentation for your specific distribution to install slapd.

Copy the provided courier.schema and dnsdomain2.schema to /etc/ldap/schema/. Start slapd afterwards. New object schemas should now be available but the config has to be regenerated.

Debian

If you are not prompted for initial configuration, you can reconfigure the package with the following command.

dpkg-reconfigure slapd

NOTE: Initial configuration must be set with a baseDN of dc=opennic,dc=glue.

2) Test Connection and Base Schema

If everything has been setup correctly, the following should work. You will be prompted for the administrator password.

ldapsearch -h localhost -D "cn=admin,dc=opennic,dc=glue" -W -b "dc=opennic,dc=glue" -s "base" "(objectclass=*)"

3) Create dnsschema.conf

Create /tmp/dnsschema.conf with the schemas you would like to use. As an example:

include /etc/ldap/schema/core.schema

include /etc/ldap/schema/cosine.schema

include /etc/ldap/schema/nis.schema

include /etc/ldap/schema/inetorgperson.schema

include /etc/ldap/schema/dnsdomain2.schema

4) Create Temp Config Directory

Create a directory to create the new LDAP configuration.

mkdir /tmp/dnsschema.d

5) Generate Temporary Config

Populate the test directory with a base config.

slaptest -f /tmp/dnsschema.conf -F /tmp/dnsschema.d/

6) Verify Config

Check and make sure the /tmp/dnsschema.d/ directory has cn=config, which should suggest that the config has been created successfully.

7) Make Necessary Changes to LDIFs

Edit the new dnsdomain2.ldif(should be at /tmp/dnsschema.d/cn\=config/cn\=schema/cn\=\{*\}dnsdomain2.ldif) in the temporary config. Change the first few lines so it looks something like the following:

dn: cn=dnsdomain2,cn=schema,cn=config

objectClass: olcSchemaConfig

cn: dnsdomain2

Edit courier.ldif in a similar fashion to look something like this.

dn: cn=courier,cn=schema,cn=config

objectClass: olcSchemaConfig

cn: courier

For both files, remove everything below the last olcObjectClasses entry as it is superfluous and possibly conflicting.

8) Merge New Schema

Now, we need to merge the new object schemas into the config.

ldapadd -Y EXTERNAL -H ldapi:/// -f /tmp/dnsschema.d/cn\=config/cn\=schema/cn\=\{3\}courier.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -f /tmp/dnsschema.d/cn\=config/cn\=schema/cn\=\{5\}dnsdomain2.ldif

If all goes well, you should see output along the lines of:

SASL/EXTERNAL authentication started

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

SASL SSF: 0

adding new entry "cn=dnsdomain2,cn=schema,cn=config"

9) Add Test Data

ldapadd -D "cn=admin,dc=opennic,dc=glue" -W -x -f opennic_glue.ldif
ldapadd -D "cn=admin,dc=opennic,dc=glue" -W -x -f test_zone.ldif
ldapadd -D "cn=admin,dc=opennic,dc=glue" -W -x -f users.ldif

A complete test environment should now be setup and ready to go.
