When I try to add the names "İsmail" (original, with dotted capital I)
and
"Ismail" (transcribed, regular capital I) to an entry using ldapmodify:
dn: ...
changetype: modify
replace: givenName
givenName: Ismail
givenName:: xLBzbWFpbA==
-
I get the error:
ldap_modify: Type or value exists (20)
additional info: givenName: value #0 provided more than once
The lowercase version of dotted and regular capital I is regular i which
explains this error. However according to unicode case folding the dotted
capital I should be mapped to 0069 0307 (i, combining dot above) which would
make Ismail andİsmail different when compared case-insensitively as I
would expect.
Apparently our liblunicode implementation doesn't use the CaseFolding data. I
believe that means our implementation corresponds to the "Simple" case folding
rules. They're valid, just not doing what you want in this case. So it appears
that this is an enhancement request.
I don't believe this request warrants a very high priority. Looking at the
Unicode charts, I-with-dot-above is the only character where the two case
folding alternatives actually makes a difference.
