Thanks Chad for your response. Let me clarify the question:

I have old LDAP AD password encryted in unixUserPassword:

unixUserPassword: CNRP!efgh12345$67899

How can I use the encrypted password in unixUserPassword format to userPassword?

If I tried to add the unixUserPassword to an ldif file:

dn: xxxxxxxxx
changetype: modify
replace: userPassword
userPassword: {crypt}CNRP!efgh12345$67899

Then run the command ldapmodify, it did not work, because it is simply
that the encrypted password "CNRP!efgh12345$67899" from
unixUserPassword is not the {crypt} format (I have no idea what the
format for the unixUserPassword is)

I have searched openldap document and Internet, could not find anwser
for what type of the encryption used in unixUserPassword and how could
I convert the password in unixUserPassword to userPassword in an idif
file. Appreciate any advice and helps.

Thank you.

Kind regards,

jupiter
