This is confusing and probably ought to be a FAQ somewhere (or maybe it
is, and I missed it).  In this case, you want to just copy and paste
the passwords from shadow and prepend a {crypt}, even though this is
an MD5 password.  For some reason, there's a difference in the MD5 that
LDAP natively recognizes and the MD5 that glibc uses, so you can import
and use {md5}.  But what happens with {crypt} is that LDAP passes the
password to the system crypt(), which recognizes it as an MD5 password
and deals with it appropriately.  And of course, this is all well and
good provided that all the systems you're providing authentication to
use glibc and pam or at any rate support this scheme of MD5 passwords.
