Hello, I'm configurating dovecot 1.0.3 on debian etch. While trying to set public folders, y decided to have the index and control files on the users homes. those homes are mounted by nfs, with disabled access to root. In that scenario, I'm getting the errors i transcribe next:

Aug 16 11:21:17 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/mailfile, /inbox/shared/.folder/cur/mailfile :2,S) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:17 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/mailfile, /inbox/shared/.folder/cur/mailfile :2,S) failed: Operation not permitted Aug 16 11:21:26 server dovecot: IMAP(user): Disconnected: Logged out Aug 16 11:21:27 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlis t) failed: Operation not permitted Aug 16 11:21:27 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/mailfile, /inbox/shared/.folder/cur/mailfile :2,S) failed: Operation not permitted

Then I touched those files and the errors faded away. Beside that, I was testing the setup, and while trying to delete some files on the shared folder, I got another error: Aug 16 16:38:04 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/1183976419.755_0.server:2,Sa, /inbox/shared/.folder/cur/1183976419.755_0.server:2,STa) failed: Operation not permitted Aug 16 16:38:11 server dovecot: IMAP(user): fchown(/home/user/Maildir/shared-settings/control/.folder/dovecot-uidlist) failed: Operation not permitted Aug 16 16:38:11 server dovecot: IMAP(user): rename(/inbox/shared/.folder/cur/1183976419.755_0.server:2,Sa, /inbox/shared/.folder/cur/1183976419.755_0.server:2,STa) failed: Operation not permitted

Which seems odd, because I though that as a flag, the deleted flag should be marked on the index files and not directly on the shared
folder (where the user hasn't any permission other than reading), ant the same goes to the "read" flag

Am I wrong? Is there any workaround to make dovecot behave the way I'd liked?

The config follows:

login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail mail_location: maildir:/home/%u/Maildir:INBOX=/inbox/mdir/%u mmap_disable: yes namespace: type: private separator: / location: maildir:~/Maildir:INBOX=/inbox/mdir/%u inbox: yes namespace: type: public separator: / prefix: Shared folders/ location: maildir:/inbox/shared:INDEX=/home/%u/Maildir/shared-settings/index:CONTROL=/home/%u/Maildir/shared-settings/control auth default: passdb: driver: passwd args: blocking=yes passdb: driver: shadow userdb: driver: passwd

Cheers, Luis
