    [SOLVED] Problems migrating shadow file from SuSE 9.3 to Ubuntu Server x86_64

    Hi

    I just migrated a server from SuSE 9.3 to Ubuntu Hardy Heron.
    I copied users from old shadow file to the new file the users can't login.
    I guess this has to do with the way users passwords are encrypted in SuSE and in Ubuntu.
    Any ideias how I can solve this problem??

    Kind Regards,

    João Seabra

    You are definitely on the right path. By default SuSE encrypts file using a blowfish algorithm. Ubuntu is probably expecting DES or MD5 depending on whether you have changed the configuration.
    Code:
    man shadow
    provides tips on determining which algorithm is in use. I am not sure how to convert from blowfish though I have only seen SuSE use that algorithm in my experience.

    libpam-unix2 - Blowfish-capable PAM module
    This solved the problem
