I have researched this and the incorrect behavior seems to be totally
caused by the fact that unquoted commas are treated as item separators
in pg_hba.conf.
I have updated the documentation in 8.2 and CVS HEAD to indicate that
the LDAP URL should be double-quoted, and double-quoted the example URL
for emphasis.
If double-quoting does not 100% fix your problem, please let us know.
Thanks.
Documentation patch attached.

! Commas are used to specify multiple items in an <literal>ldap</>
! component. However, because unquoted commas are treated as item
! separators in <filename>pg_hba.conf</filename>, it is wise to
! double-quote the <literal>ldap</> URL to preserve any commas present,
! e.g.:
<synopsis>
! "ldap://ldap.example.net/dc=example,dc=net;EXAMPLE\";
