Hi,

thanks for pointing this one out. I can fix the Cyrus IMAP RPM and APT 
packages I provide[1,2], and those that are shipped as part of 
Fedora[3], but I cannot make the call for Red Hat Enterprise 
Linux/Ubuntu/Debian.

Please also note this patch does not apply cleanly to cyrus-imapd git 
master, and could possibly not be necessary either.

Kind regards,

Jeroen van Meeuwen

Hi Jeroen,

 Fedora[3], but I cannot make the call for Red Hat Enterprise
 Linux/Ubuntu/Debian.

I sent a mail to ond...@debian.org, who did last maintenance on 
cyrus-imapd-2.4 on Ubuntu.

Re: uppercase usernames

2013-03-11 Thread Joerg Maier
Hi Dan,

Thanks for you suggestion!

Unfortunately, testing the solution i have in mind, i renamed and 
finally deleted my one CamelCase testaccount. And now, when I try to 
create a mailbox with CamelCase with cyradm, the default acls are set to 
a user with lowercase username, and I am not able to set additional acls 
to a user with CamelCase with sam.

I suppose that username_tolower: 0 just does not does what I thiought 
it did in the source installation.

The solution I want to use for my users now is:
- renaming user to lowercase in userdatabase
- renamin cyrus account with cyradm rename to lowercase
- creating a virtual forward rule, so postfix delivers the mail sent to 
CamelCase address - camelcase (and keep lmtp_downcase_rcpt: 0 and 
username_tolower: 0 until last CamelCase adress is converted.

Thanks, Joerg

Hi,

Is your system RedHat/CentOS/Fedora ?
I think their version (since 2.3.x) have a patch that normalize 
(lowercase + strip leading and trailing whitespaces) authentication ids. 
From what I could see it appears it was added as a configuration option, 
but the code is not complete and so the default value (enabled) applies.

Re: uppercase usernames

2013-03-11 Thread Joerg Maier
Hi Julien,

Thanks for the hint!

My system is (now) Ubuntu 12.04.2 LTS. I found normalizeuid in the 
docs, which I set to 0. Still with the same result.

I scanned the code a bit as well, I find such a patch in the Ubuntu 
distribution patches 
(cyrus-imapd-2.4.2-903-normalize-authorization-id.patch). If I 
understand the code, it is initialized with 0, and only if set to 1 if 
config says.

I think now, the best solution would be to install a debug version 
somewhere and see which of the 68 tolower calls in the code performs my 
unwanted tolower and why.

As I only have 20 mailboxes with UpperCase letters in them, and after 
testing I found that a combination of rename user/CamelCase 
user/camelcase plus sam user/camelcase camelcase lrswipcda plus some 
account changing in the database will fix my issue,
- without any manual configuration steps for the users
- still the rcpt to:CamelCase mails will get to the renamed account

Thanks for all your help. I guess the next person who runs into this 
and reads this thread needs to debug a bit or study the code investing 
more time.

Maybe it's the same patch than in RedHat. There the issue is that cyrus 
configuration code is separated in 2 parts: one in the core library 
(pretty much static; values accessed with 
libcyrus_config_getxxx/libcyrus_config_setxxx), the other being 
accessible in all services and populated from the content of imapd.conf 
(values accessed with config_getxxx).
The patch declares the option in both parts and uses 
libcyrus_config_getxxx to query the value because it is needed in the 
core library. From what I could see, what is lacking is a line of code - 
usually in imap/global.c:cyrus_init - do get the value from imapd.conf 
and set it in the core library, like it is already done for some other 
options. Example with username_tolower:

 libcyrus_config_setswitch(CYRUSOPT_USERNAME_TOLOWER,
   config_getswitch(IMAPOPT_USERNAME_TOLOWER));

I don't know who is in charge of this patch, but maybe Jeroen can help 
fix the issue on RedHat side. Actually he seems also linked to the patch 
on Debian ?
