[otrs] Not possible to add a note in OTRS 2.1.4

["Josep M. Salom Redó"]

Hi,

We have just upgraded from OTRS 2.0 to OTRS 2.1.4 and now is not 
possible to add a note to a ticket if altough you have rights for adding 
notes. You also need to be 'owner'. That's a functionality that was 
working in 2.0 version.

Please, could you tell us if it's needed to change something in the 
SysConfig?

Thanks in advance,

Josep
