Using sAMAccountName attribute fails to start

[mfarwell]

We're trying to use ldap-server in our CI loops and we want to test both LDAPs and ADs that use either the uid or sAMAccountName as the user Id attribute. We'd like to be able to test both scenarios with one LDIF configuration. I was hoping to simply add sAMAccountName as an attribute, but the service fails to start with the following error:

The attribute 'samaccountname' cannot be stored
Exception in thread "main" org.apache.directory.api.ldap.model.exception.LdapNoSuchAttributeException: ERR_04269 ATTRIBUTE_TYPE for OID samaccountname does not exist!

Here's the LDIF that we're trying to use:
