Bug(?) With OpenLDAP 2.3.32

[daniel@ncsu.edu]

Hi folk!

We upgraded to OpenLDAP 2.3.32 recently and I ran into something that,
unless I have completely lost my mind, should not be occuring:

/local/ldap/data # /local/ldap/bin/ldapmodify -x -h localhost -D
"cn=ldapadmin,dc=ncsu,dc=edu" -w LDAPADMINPASSWORD
dn: uid=STUDENTUSERNAME,ou=students,ou=people,dc=ncsu,dc=edu
changetype: modify
replace: ou
ou: B A - Physics
ou: B S - Philosophy
-
replace: ncsucurriculumcode
ncsucurriculumcode: PYA
ncsucurriculumcode: LSL

modifying entry "uid=STUDENTUSERNAME,ou=students,ou=people,dc=ncsu,dc=edu"
ldap_modify: Type or value exists (20)
        additional info: modify/replace: ou: value #1 already exists


Obviously I replaced the user's username and my ldap admin password.  ;D 
A replace should literally be replacing the ou and ignoring what it's
currently set to, correct?  And since those two ou's are not the same, it
should be fine?  What's even more bizarre is that I didn't run into this
while populating the database in the first place.  Is this, perchance,
fixed in 2.3.33?  Thanks!

Daniel
