Can we assume you are talking about a "clean" F18 system?  Any reason not to post in the "users" mailing list?

FWIW.....

I see no "breakage".

It broke for me. It was coincident with the change from kernel 3.7.9 to 3.8.1 but I didn't investigate if this was the cause.

Adding a "sec=" option with either ntlm or ntlmv2 worked for me. Slightly odd given that the man page says ntlm is the default.

Digging a little more, a possibly relevant kernel commit from 2012-11-25 has the comment "default authentication needs to be at least ntlmv2 security for cifs mounts":
-#define   CIFSSEC_DEF (CIFSSEC_MAY_SIGN | CIFSSEC_MAY_NTLM | CIFSSEC_MAY_NTLMV2 | CIFSSEC_MAY_NTLMSSP)
+#define   CIFSSEC_DEF (CIFSSEC_MAY_SIGN | CIFSSEC_MAY_NTLMSSP)
