(&(objectCategory=person)(objectClass=user)( !(userAccountControl:
1.2.840.113556.1.4.803:=2)))

which is something you probably aware of, already. It does not filter  out
"test" but filters out disabled accounts. so at least from that stand point
I hope this helps you.

That same filter works well in other application as well that use LDAP
access.

To expand on that LDAP filter  statement:

(&(objectCategory=person)(objectClass=user)( !(userAccountControl:
1.2.840.113556.1.4.803:=2))(!([attribute]=*test*)))

Depending on where the "test" is you would replace [attribute] with:
sAMAccountname - if the "test" value you're trying to filter out is in the
account name
description - if the "test" value you're trying to filter our is in the
description

Right now I'm shooting from the hip because I'm not in the office and can't
run a quick test  to verify. Let me know if this doesn't work or if the "test"
value you're trying to filter out is not in the account name or description.

(&(objectCategory=person)(objectClass=user)(
!(userAccountControl:1.2.840.113556.1.4.803:=2)(!(Description = *test*))))

Did not work.

Are you looking for "test" in the AD account's description or account name?

Test in description.........................

I had a paren on the wrong side of the description attribute
clause.
Try this.

(&(objectCategory=person)(objectClass=user)(!(userAccountControl:1.2.840.113556.\
1.4.803:=2))(!(description=*test*)))

Don't worry I think I got it.

(&(objectCategory=person)(objectClass=user)(!description=*test*)
(userAccountControl:1.2.840.113556.1.4.803:=2))

Position may be a key here.

You might want to also run some queries to make sure you're not excluding
legitimate users who have the letters "test" in their description like "portal
users John Beltest". Are your "test" users members of any telltale domain
groups, like a group in which you place all your test  accounts? If so, you might
consider using a query against memberOf instead of description.

Is there a way to wipe out the entire profile  database?

I did a few imports and it seems like when I go to edit a profile, it comes
up with a different user.

http://yourportal/_layouts/1033/ProfMngr.aspx?ConsoleView=Active

you can delete all the users there...

So, which one of the filters works for sure? The one from Mark, or then one
you pointed out yoruself Dave??

I'm not sure anymore.. both might not work..Still have to test..

Only problem. When I delete it from here, the next time I import, the user
(active) won't import anymore.

How would I do that for a group??????
