ldapsearch works, i can find myself using:

ldapsearch -LLL -x -H ldap://ADserver:389 -b
'ou=users,ou=yonkers,dc=mydomain,dc=org' -D 'cn=rt,ou=Service
Accounts,ou=Users,ou=HIGHSECURITY,dc=mydomain,dc=org' -w 'rtPassword'
'(&(ObjectClass=Person)(cn=Polyakov, Valeriy))'


I also turned on debug loging for externalauth, and here's what I see in
the log. the password im providing is correct, it seems to be able to find
my account, but then I get an auth failure..  why ? :/
