>Description:
Blowfish cipher password hashes look strange after creating users with adduser on FreeBSD 7.0-RC3 amd64 and i386:

user0:$2a$04$xYpywjtq..............p1dnhRzopxTA03kej/n.6zzH1IPnFnq:1001:1001::0:0:User &:/home/user0:/bin/sh
user1:$2a$04$x8Oz2mIk..............ic9QqpzeeBC/8UkJkon5pW5N5TfwDAG:1002:1002::0:0:User &:/home/user1:/bin/sh
user2:$2a$04$lmDQpxT6..............iNc5meFZZnmw7byA8rt2ouR9wHoXmua:1003:1003::0:0:User &:/home/user2:/bin/sh
user3:$2a$04$c.RmkxcN..............oy3vTt.DSXmmn4.0FmpAjXdWJ1Q/AOq:1004:1004::0:0:User &:/home/user3:/bin/sh
user4:$2a$04$wuch.t4M..............oyvIaigqtR9kp0q1M9I.y3fYHxtqHRm:1005:1005::0:0:User &:/home/user4:/bin/sh


You can fix it by using passwd to reset the passwords:

user0:$2a$04$3FigWO7CgDRWakxDPQ50leHU6739Qj3e62mymnSfKNDq8qs0B8fAi:1001:1001::0:0:User &:/home/user0:/bin/sh
user1:$2a$04$5ngJCj0kptu4Lm.i3o4d9OJpLQH6yY4TFtWwVBxTdnaTHaN0nqTm6:1002:1002::0:0:User &:/home/user1:/bin/sh
user2:$2a$04$tkQwdseohOkb83U2XJnmk.r6ghthOrPB9i4VByq8w49mpUbNsvyPq:1003:1003::0:0:User &:/home/user2:/bin/sh
user3:$2a$04$Lq5HoOpnsfSpiocSIQqdrOi2XkzXWRcBQ3grTXzEES0Mx2tP8IBAa:1004:1004::0:0:User &:/home/user3:/bin/sh
user4:$2a$04$x03.j9m1V/fP2biVVQzFJOjUYvobXaAbqAESdE6N6Y8vz6GyVwHuK:1005:1005::0:0:User &:/home/user4:/bin/sh
>How-To-Repeat:
1. change default-profile's passwd_format to blf in /etc/login.conf
2. cap_mkdb /etc/login.conf
3. change crypt_default to blf in /etc/auth.conf
4. add users with adduser
>Fix:
Reset passwords with passwd.
