What about doing ldapsearch to the base tree and redirecting it to an LDIF
and importing LDIF file to Sun DIrectory server
but there are few thing you need to take care

1. First stop samba service, so that no further user passowrd changes or
machine password changes takes place

2. Take an LDIF output by using ldap search

example :
#ldapsearch  -LLL -x  -b "dc=example,dc=com" -D
"cn=Manager,dc=example,dc=com" -W  >>> /tmp/mybackup.ldif

3. Once the LDAP information is exported to Sun Directory server, change the
ldap server ip address in smb.conf

Now there is one more part

the secrets.tdb file has the password of "DN" through which it binds to LDAP
server,  I would suggest to keep the same password for the Sun Directory
server also.

because having a different password means running "smbpasswd " command to
update it and this may cause to change the "SID" , though . so be careful

Let me know if the above helped and if any body else can comment on above
steps ,  or is there anything else i am missing.
