I wrote a test schema file adding one attribute - ipPhone.
I found some "tutorials" explaining how to write a schema file then
convert it into LDIF using slaptest(8).
The authors of these tutorials [found by me] all manually edit
slaptest(8)-generated LDIF files, removing structuralObjectClass,
entryUUID, creatorsName, createTimestamp, entryCSN, modifiersName and
Is this the recommended way of adding a schema?
