PostgreSQL pam ldap document

All,

    I visited #postgresql @ FreeNode and asked about how to make pg use pam
about a week ago (specifically I wanted to auth against LDAP).  I was
told to figure it out and write a doc...

Here is my attempt at doing so:  http://itc.musc.edu/wiki/PostGreSQL

Please review for accuracy and/or proofreading.

Thanks,

Adrian
