Unable to map attributeID

[Matthieu Patou]

Looks like a bug somewhere as if I remove the transaction I am able to 
add some objects and when the addition is OK I do not have strange 
trailing chars.

dn:CN=ACS-Max-Peak-Bandwidth,CN=Schema,CN=Configuration,DC=smb4,DC=tst 
<-- this object was causing problems before and now it's OK
objectClass:top
objectClass:attributeSchema

Any explanations ?
