My NT account hasn't special char,  but my password contain "§"
When I try to authenticate myself wia winbind I got this message : 

# wbinfo  -a 'domain\login%pa§§word'
plaintext password authentication failed
error code was NT_STATUS_WRONG_PASSWORD (0xc000006a)
Could not authenticate user domain\login%pa§§word with plaintext password
challenge/response password authentication succeeded

With another password : 

# wbinfo  -a 'domain\login%password'
plaintext password authentication succeeded
challenge/response password authentication succeeded

What's the matter ?
