which schema/objectclass I need to use?

[ericchau@hksfc.org.hk]

Hello all,

I want to add entries to ldap database but I don't know which schema or
objectclass should I need to take
slapd.conf.

I have try to include inetorgperson.schema, but the process slapd fails to
start.
The message:
/usr/local/etc/openldap/schema/inetorgperson.schema: line 144:
AttributeType not
found: "audio"

Actually, I just want to have very simple database it contain the username
and email address just like
the following example.ldif.

Which schema? Which objectclass? By the way, should anyone can point a
linker to explain the schema?

Anyone can help me?

<example.ldif>
dn: cn=David Chan,dc=example,dc=com
cn: David Chan
objectClass: inetorgperson
sn: Chan
mail: davidchan@example.com
