[389-users] Wrong password hash algorithm returned


We have a radius server that reads the userPassword-attribute from ldap
to authenticate users. There is a strange phenomenon where sometimes the
answer from the ldap-server gives the wrong password hash algorithm. Our
global password policy storage scheme is set to SSHA. When I perform a
ldapsearch as directory manager I see that the password hash for a given
user is {SSHA}inserthashedpasswordhere. But when I run tcpdump to see
what our radius is being served I see {PBKDF2_SHA256}someotherhash
around 50% of the time. Sometime another request from radius a few
seconds after the first one gives the correct {SSHA} response.

This happened right after we updated from 389ds 1.2.2 to 1.4.4.
I am a bit stumped.
