Hello,
[First of all, sorry if this question has already been answered before: the
search on this mailing list does not work currently so I haven't been able
to check.]
I need to write a filter so that when the user of my software introduces
any substring of the content of a field in any case (upper, lower or mixed
case), it finds the entry. It must work even if the user does not input a
complete word, but just a part of a word.
The field is called "supName" and it follows the DirectoryString syntax.
This means that the default matching rule is exact and case sensitive
("caseExactMatch"). But according to:
http://www.zytrax.com/books/ldap/apa/types.html
, this syntax should allow also "caseIgnoreMatch" and
"caseIgnoreSubstringsMatch" matching rules. I though I just needed to force
to use the last one ("caseIgnoreSubstringsMatch"), so I tried this filter:
(supName:caseIgnoreSubstringsMatch:=*somesubstring*)
But this does not work. I make my tests using Apache Directory Studio, and
that tool refuses to accept the above filter. It complains on the
asterisks, and I don't understand why, since I am using a Substring match
(and thus asterisks should be allowed). If I run the filter from command
line (using ldapsearch), I get this error message:
ldap_search_ext: Bad search filter (-7)
Therefore this is not an issue with Apache Directory Studio.
So my question is: What is the correct way of defining a case-insensitive
substring filter on a field that is case-sensitive by default?
Yesterday I filled a question in StackOverflow regarding this same issue.
There are more details and examples in that question:

Any help would be greatly appreciated !
Thank you very much.
Nicolas
