You need to make sure that your schema supports all the
objectClasses and attributeTypes that the user account
template uses, namely:

'top', 'person', 'posixAccount', 'shadowAccount',
'inetOrgPerson'

And all of their attributeTypes.

Thank you for posting this Problem/Solution. I had the same
error and found the solution here.

Thank you! I assumed it has to be something wrong with the
schema but couldn't find the fault immediately.

LDAP_UNDEFINED_TYPE: Indicates that the attribute specified
in the modify or add operation does not exist in the LDAP
server's schema

I have got the same behavior today after compiling and
starting openldap 2.2.13 but I haven't fully checked my
slapd.conf. After taking a look at my standard slapd.conf
I've noticed that it includes just the core.schema you have
to inlude there the cosine.schema, the inetorgperson.schema
and the nis.schema
