No connect permissions............. please help!

I've got this strange problem... When I login to a Unix box (Sco) with the login X123 and try to run SQL I get the following error message: -------------- SQL Statement error number -387 No connect permission. SYSTEM error number -111 ISAM Error: no record found. --------------- BUT, if I 'telnet' to the same box, and login using the same user - all is fine. It is perhaps something to do with environmental variables - but don't know cure. Any help appreciated - PLEASE e-mail direct. -- Regards, E-mail: saltash@btinternet.com ---------------------------------------------------------------------------- --------------
