IMAP sessions quit when calling MYRIGHTS on shared namespace

[Franz Knipp]

Hi,

  the IMAP connection is dropped, when I call MYRIGHTS on the root of my
shared folders.

Using the configuration below, the shared folders are located in shared/%%U/

# telnet localhost imap
Trying ::1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
IDLE STARTTLS AUTH=PLAIN] Dovecot ready.
. LOGIN XXXXXXX xxxx
. OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE

ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY
MOVE QUOTA ACL RIGHTS=texk] Logged in
. MYRIGHTS shared
Connection closed by foreign host.

I'd expect some kind of error message instead of dropping the connection.

Kind regards,

Franz
