It is output directly from wireshark. Indented lines represent response
from server.

output from command ldapwhoami is in the attached file screenlog.2
but it loks like ApacheDS does not support LDAP_EXOP_WHO_AM_I.
The point was to show a Bind request using the ppolicy control. The actual
WhoAmI operation was irrelevant. But you didn't specify ppolicy in your
invocation. Please read the ldapwhoami manpage.
Use -E ppolicy to use the ppolicy control, the screenlog you attached has
nothing interesting without the ppolicy traffic.

If I read draft "6.2. Response Control" correctly,
http://tools.ietf.org/html/draft-behera-ldap-password-policy-10#section-6.2
response can be sequence of "PasswordPolicyResponseValue".
I think that sequence means "0 or more values"
The sequence is required to begin with a Sequence marker.
In theory, there needn't be any password policy response value
after control
type. In this case, either my patch or your patch are wrong.
Did I miss something?
The controlType is 1.3.6.1.4.1.42.2.27.8.5.1 and the controlValue is
the BER encoding of the following type:
"the controlValue is the BER encoding of a Sequence." - even if the sequence
has zero members, it cannot be omitted.
PasswordPolicyResponseValue ::= SEQUENCE {
warning [0] CHOICE {
...snip... } OPTIONAL,
error [1] ENUMERATED {
...snip... } OPTIONAL
}
Thank you very much for response.
