Bug#462741: lprng: No longer supports kerberos5 authtype

[Tim Abbott <tabbott@MIT.EDU>]

Package: lprng
Version: 3.8.A~rc2-1
Tags: patch

In versions of lprng before the kerberos4 authtype was deprecated, 
authtypes of the form "kerberos*" for * different from 4 were handled as 
the standard "kerberos" authtype; below is part of the diff between the 
current Lenny and Sid versions in common/user_auth.c:

 # if defined(MIT_KERBEROS4)
        { "kerberos4", "kerberos", IP_SOCKET_ONLY, Send_krb4_auth, 0,0,0 },
 # endif
-       { "kerberos*", "kerberos", IP_SOCKET_ONLY, 0,           Krb5_send, 0, Krb5_receive },
+       { "kerberos", "kerberos", IP_SOCKET_ONLY, 0,           Krb5_send, 0, Krb5_receive },
+       { "kerberos5", "kerberos", IP_SOCKET_ONLY, 0,           Krb5_send, 0, Krb5_receive },
+       { "k5conn", "kerberos", IP_SOCKET_ONLY, 0,           Krb5_send_nocrypt, 0, Krb5_receive_nocrypt },
 #endif

        { "test",      "test",     0,              0,           Test_send, 0, Test_receive },

This change breals printcap entries that specify authtype "kerberos5", 
which used to work and was a reasonable parallel to the now-deprecated 
authtype "kerberos4".

Attached is a small patch to cause authtype "kerberos5" to restore support 
for the "kerberos5" authtype.
