[389-users] case sensitivity and matching rules

[Christopher Wood]

I'm puzzling over case-sensitivity, attributes, and matching rules in 389.

I have an attribute (oid slightly munged for privacy):

attributeTypes: (
1.2.3.4
NAME 'ldapAuthLogin' 
DESC 'Account login name' 
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 
SINGLE-VALUE 
X-ORIGIN 'user defined'
)

It doesn't look like there's a matching rule associated with this.

How does 389 decide which matching rules to apply here?

(In this case, per ldapsearch, it seems to be a case-insensitive string match.)

My apologies if this is obviously answered somewhere, I've pored over the docs 
and the mailing list archives and haven't found it yet.

For Directory String (1.3.6.1.4.1.1466.115.121.1.15) and related 
syntaxes, it uses case insensitive compare.
 (In this case, per ldapsearch, it seems to be a case-insensitive string 
 match.)

Attributes really should define EQUALITY, ORDERING, and SUBSTR matching 
rules instead of relying on the default behavior.
