Changing a password type from Crypt to Open Directory

Hi,

Does exist a command line to do change a password type from Crypt to Open Directory ?

I want to automate the creation of LDAP user. For the moment I have this :

dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" cn "$login"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" sn "$login"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" uid "$login"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" gidNumber "$gid"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" uidNumber "$uid"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" homeDirectory /Volumes/data/"$login"
dscl -u ADMIN -P "PASSWORD"  /LDAPv3/127.0.0.1  -create /Users/"$login" loginShell /bin/bash

With :

$ pwpolicy   -a diradmin -p "(paradize)"   -u "test9"  -n  /LDAPv3/127.0.0.1 -setpassword "aa"   
test9 is not a password server account.

Thanks
