No need to login and copy stuff, just point ipa-getkeytab at the other
master with the -s switch. Once you've done that, restart the replica,
however there are chances it will then try to get a TGT to replicate
against the local KDC and it will fail because the local KDC has the old
key. One way to help this is to temporarily change krb5.conf to
explicitly point to a "good" replica so that KDC operations will be
handled by that other replica, restart all IPA components and make sure
a round of replication happens. Then restore the krb5.conf file and

If the play above doesn't help, it will be simpler to reinstall the
