Yes I can confirm that CRYPT will work!!
Would love to see an update that supports SSHA, since this has been a defacto hashing standard in a few directories for some time.
What is super important that whatever administrative username you are using needs to have the ability to read the password hash attribute. You can easily test to see if you have the permissions to the password attribute with getXXbyYY.
filer9*> getXXbyYY getpwbyname_r gunn
pw_name = gunn
pw_passwd = saltsaltABCDEF
pw_uid = 1000, pw_gid = 1000
pw_gecos = Paul gunn
pw_dir = /home/gunn
pw_shell = /bin/bash
If you don't have the correct permissions, the pw_passwd will always show up as pw_passwd = {{******}}
