I suspect you're going to need to add the CA that issued your LDAP 
server certificate to the IPA Apache NSS certificate database (where our 
admin framework runs).

You'd add it something like this:

# certutil -A -d /etc/httpd/alias -n 'LDAP CA' -t CT,C,C -a < 
/path/to/ca.crt

The -n 'LDAP CA' adds a nickname to the CA. There is nothing special 
about this, it just needs to be unique. Use something meaningful to you.

Then restart the httpd service and try the migration again.

I don't know if we've tested using ldaps, so if my suggestion works can 
you let us know?
