Hi all,
Is there someplace other than then OpenLDAP admin guide which
explains the BDB indexing directives? What's there isn't all that
helpful, e.g.:
- what does it mean to maintain a 'present' index
The attribute exists (a worthless index if there ever was one).
- an 'equality' index (or approx/sub) ?
eq -- You can do equality matching on the value of the attribute. i.e, you
can filter on uid=quanah
sub -- You can do substring matching on the value of the attribute. i.e.,
you can filter on "cn=quanah*mount"
approx -- You can do approximate (or phonetic searches, if compiled that
way) on the value of the attribute. i.e., you can filter on
"sn=~gibson-mound"
- what are the 'default' indices maintained if
There are no default indices maintained. You need to specify what to
index. You can specify a default type of indexing, i.e.,
index default eq
index uid
index sn eq,sub,approx
index cn eq,sub
Will index uid with eq, sn with eq,sub,approx, and cn with eq,sub
