Re: uniqueMember and nameUID* issues (ITS#3210)
Another related issue: currently, we assume that a nameUID string
terminated by "'B" contains an ID; I think that unless we're able
to isolate a terminal part made of an unescaped "#" followed
by "'", a bistring, and terminated by "'B" we should treat the whole
string as a DN unless explicitly violating DN string encoding.
I note that "cn=Foo#'1'B" is perfectly legal as a DN
as well, since the character "#" doesn't need to be escaped
except at the beginning of the value part of an AVA in a DN.
So, based on the string representation, a nameUID is valid
as a DN as well. As such, I think we should remove the test
for an escaped number sign when extracting the UID part of a
nameUID, and treat it as a DN instead of failing when
cn=Foo#'1'B // legal DN + UID = 1
cn=Foo#1'B // legal DN?
cn=Foo\#'1'B // legal DN without UID ("#" may be escaped)
cn=Foo#'2'B // legal DN?
cn=Foo#2B // legal DN?
