Authorization problem

Hello!

The news server I use doesn't allow to post articles with tin or Gnus. 
It requires authorization, so I wrote ~/.newsauth file and run
`rtin -A' but tin falls saying 'Authorized for user: USERNAME', then 
'Permission denied'.


Telnet says this:

% telnet www.830.ru 1119
Trying 195.2.82.10...
Connected to diasp.ru.
Escape character is '^]'.
201 830.ru InterNetNews NNRP server INN 2.4.3 ready (no posting).

I can say 'authoinfo user ...' and 'authoinfo pass ...' then server says 
Ok and I can post.  But tin can't do this for some reason.  Maybe it 
pays attention on 'no posting' string in server's output to telnet...
