I'm running 4.91 SP5 on Windows XP SP3.
Trying to change the password logged in as a user that doesn't have a
universal password policy and when I have NMAS Authentication = ON I
get the error -1665 NMAS_E_LOGIN_ATTRIBUTE_NOT_FOUND when I look in the
Wireshark trace, i.e. I can't change the password. Turning off NMAS
Authentication doesn't give me this error.

Shouldn't the password change work without regard if I have a UP policy
or not?

We tested on a colleagues computer with an older client (SP4 I think on
Windows 2000) and there the password change works even with NMAS
Authentication set to ON.

Any ideas?
