OK, I take it, that if you now run 'sudo net ads testjoin', it returns
'Join is OK'.
If it isn't, then you need to find out why your computer isn't joined
to the domain.

Turning to the fstab line you posted earlier:

//winnas/radio /radio cifs
credentials=/etc/samba/credentials/radiorec,vers=2.0,uid=1000,gid=1000,iocharset=utf8,sec=krb5i,nofail
0 0

It appears you are trying to use a credentials file and kerberos, you
do not use both.

To use kerberos, try it like this:

//winnas/radio /radio cifs
uid=1000,gid=1000,iocharset=utf8,sec=krb5i,nofail 0 0

To use your credentials file, try it like this:

//winnas/radio /radio cifs
credentials=/etc/samba/credentials/radiorec,uid=1000,gid=1000,iocharset=utf8,nofail
0 0

If your machine is joined to the domain and the share will still not
mount via fstab, try mounting it manually.
