I have been recompiling openssh to allow Active Directory/kerberos based logins. This depends on having kerberos installed. This is not a standard Slackware setup, so take this for what it is worth.
I have been preparing a baseline setup to test Slackware 14.1. I ran into a an issue that was preventing an Active Directory user from logging in, but not a local user with either a key or a password.
The solution appears to involve toggling a sshd_config parameter to use a non-default value:
The default using "sandbox" fails the login for some reason. For comparison the default configuration works on a similar Slackware 14.0 box. This works fine there:
The difference in packages are summarized below.
Slackware Version openssh priv sep krb5 from MIT
14.0 6.1p1 sandbox 1.9.5
14.1 RC2 6.3p1 yes 1.10.6
