I am currently in the process of migrating from a LDAP server to IPA installed on a Centos 8 instance.

I been following these instructions on importing users from the LDAP server https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/linux_domain_identity_authentication_and_policy_guide/using-migrate-ds but it's asking for the Directory Manager password, I took over position very recently  and there is a password which is supposed to be for that account but it's not accepted.

Is it possible with the ipa migrate-ds to specify another user, i'd say no since the docs doesn't mention anything but I thought that I ask, or is it possible to use a ldif file to import the users?
