[Dovecot] alpha4: flock change
by Jeff A. Earickson 20 Oct '05

20 Oct '05

Timo, The comments in dovecot-example.conf regarding lock_method for Solaris users needs to note your change. Your changelog says: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. But there is no warning about this in the file for Solaris users. There should be; it will bite somebody later. Jeff Earickson Colby College

[Dovecot] [PATCH] Support for GSSAPI SASL Mechanism
by Jelmer Vernooij 20 Oct '05

20 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Attached is a patch against current CVS that adds support for the GSSAPI SASL mechanism. It was written from scratch, after reading the patch from Colin Walters against a much older version of dovecot. Other then support for the 'GSSAPI' mechanism, it contains the following changes: - - Added 'auth_krb5_keytab' option for overriding default keytab location. The gssapi library already uses the environment variable KRB5_KTNAME to allow overriding of the keytab location, so I didn't have to make any changes on the login process side. - - Added 'need_passdb' member to mech_module and allow having no passdb's specified if no mechanisms need them (only useful for GSSAPI at the moment) Cheers, Jelmer - -- Jelmer Vernooij <jelmer(a)samba.org> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFDVgaEPa9Uoh7vUnYRAscGAJ9Fa4E5ze5IX3UeAfjwg7kzj5tgtQCcDva7 O5VTeOeJ7zpmHullxQN6q1Y= =60w7 -----END PGP SIGNATURE----- Index: configure.in =================================================================== RCS file: /home/cvs/dovecot/configure.in,v retrieving revision 1.214 diff -u -r1.214 configure.in --- configure.in 23 Sep 2005 13:28:40 -0000 1.214 +++ configure.in 19 Oct 2005 08:25:31 -0000 @@ -118,6 +118,15 @@ fi, want_bsdauth=yes) +AC_ARG_WITH(gssapi, +[ --with-gssapi Build with GSSAPI authentication support (default)], + if test x$withval = xno; then + want_gssapi=no + else + want_gssapi_yes + fi, + want_gssapi=yes) + AC_ARG_WITH(ldap, [ --with-ldap Build with LDAP support], if test x$withval = xno; then @@ -1192,6 +1201,17 @@ ]) fi +have_gssapi=no +if test $want_gssapi = yes; then + AC_CHECK_PROG(KRB5CONFIG, krb5-config, YES, NO) + if test $KRB5CONFIG = YES; then + AUTH_LIBS="$AUTH_LIBS `krb5-config --libs gssapi`" + AUTH_CFLAGS="$AUTH_CFLAGS `krb5-config --cflags gssapi`" + AC_DEFINE(MECH_GSSAPI,, Build with GSSAPI support) + have_gssapi=yes + fi +fi + if test $want_ldap = yes; then AC_CHECK_LIB(ldap, ldap_init, [ AC_CHECK_HEADER(ldap.h, [ @@ -1486,5 +1506,6 @@ echo "Building with IPv6 support .......... : $want_ipv6" echo "Building with pop3 server ........... : $want_pop3d" echo "Building with mail delivery agent .. : $want_deliver" +echo "Building with GSSAPI support ........ : $have_gssapi" echo "Building with user database modules . :$userdb" echo "Building with password lookup modules :$passdb" Index: dovecot-example.conf =================================================================== RCS file: /home/cvs/dovecot/dovecot-example.conf,v retrieving revision 1.155 diff -u -r1.155 dovecot-example.conf --- dovecot-example.conf 16 Oct 2005 14:59:12 -0000 1.155 +++ dovecot-example.conf 19 Oct 2005 08:25:31 -0000 @@ -568,9 +568,13 @@ # automatically created and destroyed as needed. #auth_worker_max_count = 30 +# Kerberos keytab to use for the GSSAPI mechanism.

Hello all! I have moved from Courier-IMAP to Dovecot some month ago. It is quite stable on everyday use (1.0alpha4) but it has constant problems with large IMAP/SSL operations. We use Maildir format. For example if I select 400 messages, mark them deleted and use "purge command" in Thunderbird (to actually delete them) TB starts to do something and runs and runs and runs....Then I get script timed out errror and I have to restart TB. That never happened with Courier-Imap. Same thing happens for example moving 1000msgs to another folder or something like that. Another thing is still that from time to time dovecot indexes get corrupted and users can't access some folders. Then I have to delete dovecot* in that Maildir folder and it works again. Any thoughts on that please? BR, Alen

[Dovecot] Alpha1..2.. and 3 with Tru64
by Alfonso Sparano 20 Oct '05

20 Oct '05

Hi all, I've found a little problem to compile dovecot on a tru64 os v5.1. The problem is the lack of the "inttypes.h" into the included header in the project. Without this include the make process will fail because it can't find the uint32 type. So is sufficient to add the line '#include <inttypes.h>' in the src/lib/lib.h of the tgz distribution package.

[Dovecot] passwd and virtual users
by Erick Perez 20 Oct '05

20 Oct '05

Hi, im runnign dovecot 0.99.14 with standard pop3 auth and a default .conf file. Everything works fine. But now I need to enable virtual users for several domains in the same server while keeping the local auth. my postfix is already working for the virtual domains. What do i need to modify to enable /etc/passwd auth (already done) and virtual domains auth? in the virtual part, i have no idea. Thanks, -- ------------------------------------------- Erick Perez

[Dovecot] Failed authentication to a mysql database (bug or PEBKAC?)
by jigen 19 Oct '05

19 Oct '05

Hi, dovecot has a little crazy behaviour connecting to a mysql db: if you specify "127.0.0.1" as host instead of "localhost" it seems to work, also with a password. BUT, if you assign host=localhost without a password, it works too (as Ger Visschers says).... One more question: how I can specify more different mysql-db conteining different users? I try in the following way: passdb sql { args = /etc/dovecot/dovecot-mysql_django.conf args = /etc/dovecot/dovecot-mysql_debord.conf } and also: passdb sql { args = /etc/dovecot/dovecot-mysql_debord.conf } passdb sql { args = /etc/dovecot/dovecot-mysql_django.conf } but it always seems to remember only the last args value and it tries to connect only one db... bye jigen -- jigen <jigen(a)metalabs.org> MeTA~LAbS

[Dovecot] Message not found errors
by Andrew Hutchings 19 Oct '05

19 Oct '05

Hi, I'm getting a very small amount of users getting message not found errors while downloading mail via POP. By the time they inform me and I switch on rawloging for them it works again. Any ideas where this is going wrong? Or at least a way I can diagnose it? It seems to have been happening since Alpha 1. Currently using pre-release of Alpha4.

[Dovecot] Pocket Outlook weirdness
by Vadim Zaliva 19 Oct '05

19 Oct '05

Hi! I am trying to access my IMAP server running dovecot from my Pocket PC running PocketOutlook. I observe very strange behavior: it starts to fetch messages from INBOX and shows list them on the screen as it fetches, then all messages disappear from the screen and it says "fetching folders". After the end of update operation it shows me empty list of messages. Have anybody have seen such problem? In general, are there reports of successful pocket outlook + dovecot users? Any suggestions are appreciated! I really want to make this thing work. Sincerely, Vadim
