So, how would one construct an LDAP query against eDir to find say,

all cn's that contain an underscore?

Apparently:
cn=*_*
doesn't work
Nor does:
cn=*_
or
cn=_*

And looks like eDir doesn't support "approximates" like"
cn~=_

or whatever?


And, let's say I want to get a list of ONLY things that have multiple values for an attribute, but I have no idea what the values are? I know how to search for say:
value1 and value2

Basically I need to find all objects that have multiple cn's
