A few more things to check: 

1. With a lot of versions of TCPIP SSH the key files must be in stream_lf 
   format, to be checked by dir/full, check the following lines in the output:
...
Record format:      Stream_LF, maximum 0 bytes, longest 32767 bytes
Record attributes:  Carriage return carriage control
...

If that is not the case, convert them to stream_lf format by
convert/fdl="file;org seq;record;format stream_lf;" <wrongformatfile> <stmlffile>.

Check the output files again with dir/full, to be sure.


2. the keys private and public have to have the following format:

---- END SSH2 PUBLIC KEY ----

If not, convert them using a ssh-keygen tool on Linux or PuttyGen.
I didn't check, but last time I looked that wasn't possible with TCPIP
ssh_keygen.
