I have a Solaris server that I am attempting to join to the domain, but the
method it supports require this unixUserPassword field to be synced with the

The method I have to use is option 2 on that page (Kerberos + LDAP). For this
server, winbind is not an option. This blog post describes how Microsoft AD
handles populating this attribute, with this "Password Sync" component:
How can I populate this field with Samba4?
