RFC 1274 defined an attribute, numbered under the pilot OID space, with 
string syntax called "uniqueIdentifier".  This document was published as a 
Proposed Standard in late '91.

X.520(1993) defined an attribute, numbered under the X.500 space, with 
BIT STRING syntax.  ITU/ISO called this attribute 'uniqueIdentifier'.  

In LDAP, deployments had been using the textual names in RFC 1274.  In
LDAPv3, we wanted to add attributes from X.520(1993) and later. To minimize
conflicts in the string names, in RFC 2256 we assigned a string name 
'x500uniqueidentifier' for the attribute defined by X.520(1993).  Section 5.46
of this document states that this attribute is distinct from both the 'uid'
and 'uniqueIdentifier' attributes, both of which are in 1274.
