refint does not alter the value of an attribute to refint_nothing when the last
"member" of a group is deleted.  refint is working when the dn of a member is
modified.

slapd.conf:
loglevel 16383
...
moduleload refint
...
overlay refint
refint_attributes member uniqueMember seeAlso
refint_nothing cn=Manager,dc=math,dc=arizona,dc=edu
...

ldap.log (what I believe to be the relevant entries):
