I have a problem with 3.8.2 and 4.0.3. If I load only one key in pageant I can login to an AIX machine.
If pageant has 2 keys in memory, the connection fails.
Strangely enough this only happens for one machine, a similar machine with same AIX (5200-02) and sshd version does not exhibit this behaviour, I can login there even if pageant has 2 keys in memory.
In "View keys" the wrong key which does not match the public key on AIX is listed first, but I cannot tell if this matches the "key #0" from the logfile below (although I guess so):
