Description of problem:

This issue is similar to this bug fixed some time ago:

https://fedorahosted.org/389/ticket/48223

for winsync.

In this case DN normalization at import time is considering that, for instance,
these two dn's are duplicated:

================================
dn: cn=user nuevo,ou=people,o=redhat
objectclass: inetorgperson
cn: user nuevo
sn: usernuevo
userpassword: user49

dn: cn=user  nuevo,ou=people,o=redhat
objectclass: inetorgperson
cn: user  nuevo
sn: us
userpassword: user49
================================

errors:

[04/Jan/2017:15:02:50.356169698 +0100] entryrdn-index - _entryrdn_insert_key:
Same DN (dn: cn=user nuevo,ou=people,o=redhat) is already in the entryrdn file
with different ID 53.  Expected ID is 54.
[04/Jan/2017:15:02:50.399342349 +0100] import userRoot: Duplicated DN detected:
"cn=user nuevo,ou=people,o=redhat": Entry ID: (54)


To reproduce, just import both entries in the same ldif file.

not sure if this is, in fact a feature (it does not seem to me from rfc4514) or
if fixing this could break something else.

If this is not corresponding or too risky, let's close this.

Thanks.
