[R] Lmer, P-values and mixed logistic regression

[Julien]

Hi
I know that p-values doesn't appear anymore in the summary of a linear 
mixed-model with lmer. However, if I do a mixed logistic regression with 
lmer using family=binomial, the summary includes a p-values for fixed 
effects.
Is it normal, could I use those p-values to interpret the fixed effects 
or should I use mcmcsamp to obtain 95% confidence interval?
Thanks
Julien
