Stefan Zoerner commented on DIREVE-307:
---------------------------------------

I tried to reproduce this one, and was able to. 
It occurred with the client tools provided by OpenLDAP, but not with the 
command line tools provided by Solaris9 and IBM Tivoli Directory Server 6.0. 
I am still trying to understand, what the OpenLDAP client does, if blank lines 
are provided. 
Btw.: the other tools behave totally different.

> When specifying multiple entries for ldapmodrdn operation, according to the 
> manual page (http://linuxcommand.org/man_pages/ldapmodrdn1.html) "one or more 
> blank lines may be used to separate each DN/RDN pair." However, it seems that 
> currently ApacheDS does not allow any blank lines in the ldapmodrdn input.

> The following operation currently will succeed in renaming both entries.
