Hi,
Has anyone tried the user_user authentication demo? When I ran it (on my
Sparc running SunOS 4.1.3) I got the following, unpleasant response.
[ 162 ] user_user -: uuserver &
[2] 10600
[ 163 ] user_user -: uuclient delhi
uu-client: client principal is "jaegert@FOO.COM".
uu-client: sending 242 bytes
uu-server: client principal is "jaegert@FOO.COM".
uu-server: client ticket is 226 bytes.
uu-server: Key size is incompatible with encryption type encoding message to client
server is named "jaegert@FOO.COM"
[2] Exit 6 uuserver
uu-client: Software caused connection abort reading reply from server
I ran gdb on the code and found that the keyblock used for encoding the
message in krb5_mk_safe_basic is being overwritten during encode_krb5_safe.
This overwrite occurs in the bowels of the asn1 encode subroutines. I can
provide a complete gdb trace if necessary.
Thanks,
Trent.
