i had a strange problem when connection from mac os x 10.6 (snow leopard) to my samba share.
Only possibility to connect was to set Security to share and enable guest account to completely disable password protection.
When Security was set to user there was always the same error:
mount_smbfs: server rejected the connection: Authentication error
After hours of trying i found out that for some unknown reason you must enter the username in uppercase letters.
so the mount command looks like
mount_smbfs //USER:password@Router_ip/share mountpoint
hope that helps someone else running into this issue
