ssh authentication failures

[networkbo]

Hi all,
I tried to activate ssh connection to cisco switches to backup configurations, authentication always fails, but I'm sure about users I configured. I try with an old cisco switch, 2950.
I use Nedi 2.0.120.
Has nedi known issues with special characters in password?
Thank you in advance for any suggestion.

There was a problem in nedi.conf, I had
uselogin        (Password)\s?:\s?(\x1b\[[;\?0-9A-Za-z]+)*$
in section "Regexp to match username prompts"
Deleting that line, authentication started to work correctly
