cifs mount in fstab no longer works

[Joseph L. Casale]

I just did a yum update and now my cifs mount in my fstab no longer mounts
at boot automatically and messages contains no errors.

I recall the _nnetdev option from a while ago but removed it as it was no
longer used AFAIK and adding back in confirmed that, messages shows it as
unknown.

fstab is as follows for this mount:
//10.0.0.5/Data         /home/xxx/Samba     cifs    username=xxx,password=xxx,uid=500,gid=500    0 0

Any ideas what may have changed?
Thanks,
