/var/run is the correct ancestor in the directory hierarchy. According
to section 5 of FHS "System programs that maintain transient UNIX-domain
sockets must place them in this directory [/var/run]". The fact it is
also segregated into a subdirectory hierarchy by component name is also
encouraged by FHS.

uid is appropriate, I am less certain gid is an appropriate attribute to
be considered during a bind. Correct me if I'm wrong, but group
membership is not considered in any of the other bind mechanisms. Isn't
bind essentially "authentication" for which the uid in this constrained
case of OS certified credentials would be sufficient to assert
authentication? OS group membership is a form of OS "authorization"
which is not part of the LDAP bind authentication. The directory
maintains it's own notion of group membership once the bind operation
succeeds in authenticating the user thus establishing the user's group
membership.
