First, lmer uses maximum likelihood as a default, while MIXED uses restricted maximum likelihood (REML). So you might add method=ml to the PROC MIXED statement. The other is to change the random effect to specifically fit random intercepts: random intercept/subject=id.

WebbLinear Mix Models, as implemented in SAS’s Proxy Mixed, SPSS Mixed, R’s LMER, and Stata’s xtmixed, are an extension of this general linear model. They use more sophisticated techniques for estimation of parameters (means, variances, regression corollaries, and standard errors), and than this quotation my, are much more flexible.
