Bug in conditionals to assign values to variables?
Hi,
According to https://wiki2.dovecot.org/Variables you could use conditionals to assign values to a varible. The syntax is:
%{if;value1;operator;value2;value-if-true;value-if-false}
where any of the fields can refer to another field using %v or %{value} syntax.
The problem is that when I use a config like:user_attrs = ...,=relpath=%{if;%u;eq;somevalue;valuetrue;valuefalse}
it works without any problem. But when I use:user_attrs = ...,=relpath=%{if;%{user};eq;somevalue;valuetrue;valuefalse}
then it reports in logs:Sep 28 14:23:22 myotis60 dovecot: auth: Error: var_expand_long(if;%{user}) failed: if: requires four or five parameters, got 1
anyway, the variable is correctly initialized, but I get the log.
Is this a bug?PS: I'm running dovecot 2.2.33

I can't seem to be able to reproduce this, not even with v2.2.33. It simply works without logging any errors.

I've made a lot of changes now. I can't neither reproduce it anymore :-(.
If I could, I'll send the complete configuration.-- Angel L. Mateo Martínez Sección de Telemática Área de Tecnologías de la Información y las Comunicaciones Aplicadas (ATICA) http://www.um.es/atica Tfo: 868889150 Fax: 868888337
Sorry for my last mail. I didn't save the file before reloading dovecot.passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap }
userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap }
auth_debug =yes auth_verbose =yes
In dovecot-ldap-userdb.conf.ext I have:user_attrs = =user=%{ldap:mail},=quota_rule=%{ldap:quota:*:storage=10G},=home_prefix=/mail/mailboxes/%L{domain},=index_prefix=/mail/indexes/%L{domain},=relpath=%{if;%{username};~;^.+;%2L{username}/%L{username};other_value}
