solaris pam vs. padl.org pam for ldap

[Adam Shand <larry@spack.org>]

question.

i'm about to install a bunch of solaris 8 boxes to do all authentication
from ldap via pam.  it looks like solaris 8 has native support for this
but there seems to be scant documentation about how to actually do this.

there is also the pam_ldap module from padl.org which seems to provide a
similar feature.

does anyone have any opinions as to which is the better solution?  
better documented, more stable etc?

thanks,
adam.
