Search case sensitivity

Are the search functions for Net::LDAP and Net::LDAP::LDIF case
sensitive?

There are several DN's in my LDAP that have mixed cases.  The LDAP is
very large and I do not want to miss any entries.

No.  LDAP searches are not case sensitive.  The Directory remembers case, an
d
returns entries as they were put into the Directory, but searches are not ca
se
sensitive.

Your LDAP server determines the sensitivity of case based on the
attribute syntax of the attributes you're searching for.  For most
"standard" textual attributes like cn, searches are not case-sensitive
(unless you've (foolishly?) configured your LDAP server differently).
Other attributes may have more complicated matching rules.

How about the LDIF.  This is a text file.  Is the search case sensitive?

That's not true. Directories support both case-insensitive and
case-sensitive matching rules.

Most commonly used attributes have associated case-insensitive matching
rules.

There are no search mechanisms defined for LDIF files, so case sensitivity
is up to you..

Cheers,

Yes, you are correct.  I was contemplating amending my response after
Christopher Bongaarts replied with the correct answer.  I will do so in the 
future.

And yes, most commonly they're not case sensitive, which is why I originally
replied saying that it's not case sensitive.  Case sensitive searches are fe
w
and far between (ordinarily).
