Hello, thank You for helping me. I did not remember the version before the update. I use FreeBSD 11.0. The OS tells me, from time to time, there are updates to do.
So it was and I have also compiled dovecot via the FreeBSD ports system with some others. These are my settings: [/usr/ports/mail/dovecot2] => make showconfig ===> The following configuration options are available for dovecot2-2.2.30.2: DOCS =on: Build and/or install documentation EXAMPLES =on: Build and/or install examples KQUEUE =on: kqueue(2) support LIBWRAP =on: TCP wrapper support LZ4 =off: LZ4 compression support VPOPMAIL =off: vpopmail support ====> Database support CDB =off: CDB database support LDAP =on: LDAP protocol support MYSQL =on: MySQL database support PGSQL =off: PostgreSQL database support SQLITE =off: SQLite database support ====> Full text search plugins ICU =off: Use libicu for FTS unicode normalization LUCENE =off: CLucene FTS support SOLR =off: Solr FTS support TEXTCAT =off: Libtextcat FTS support ====> GSSAPI Security API support: you have to select exactly one of them GSSAPI_NONE =off: Build without GSSAPI support GSSAPI_BASE =off: Use GSSAPI from base GSSAPI_HEIMDAL=off: Use Heimdal GSSAPI from security/heimdal GSSAPI_MIT =on: Use MIT GSSAPI from security/krb5

Today the error has gone. I DO NOT know why.

Yesterday I had make some more other updates for i.e. for llvm... + openjdk7.... with # portupgrade -r ( r means recursive). It takes very long time and the terminal-session was broken so the connection was lost.

Today I come back and take a look. it seems that it has finished and I go on to find out the dovecot error. I do then: #gdb --args /usr/local/libexec/dovecot/imap -u <username>@domain.tld

But "auth" like this: " Error: auth: environment corrupt; missing value " was no more broken. But there was some rights not ok for the users db. I changed this and try again #gdb --args /usr/local/libexec/dovecot/imap -u <username>@domain.tld

wow: I get a login. Then without changing any settings in dovecot I try the Outlook client............ .........and it works ???

I don't know what it was. I could not figure out what was the authorize problem because of to less debug information. When I have not program this software an error message like this "Fatal: Couldn't connect to auth socket" is not very helpful, also there are in /var/run/dovecot 7 auth sockets and more then 38 sockets in all ?!

If you have an idea, how I could better debug this please tell me. But again, thank for trying helping me.

After done an update to dovecot-2.2.30.2

my connection is broken since days.

all what I try every time the same error:

Jun 15 00:02:18 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Jun 15 00:02:18 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Jun 15 00:02:18 master: Error: service(auth): command startup failed, throttling for 2 secs Could you post the output of "doveconf -n". Please also describe from which version you upgraded to v2.2.30.2 and how you did the upgrade? Are you compiling Dovecot yourself? What are the configuration & compilation options etc.

br, Teemu

I try this:

# doveadm -Dv auth test -x service=imap theusername mypassword

output:

dlopen() failed, Undefined symbols ... Is this a bug?

How do I check what is going wrong with this auth socket error?

2nd) I'm using

dovecot.conf protocols = imap lmtp !include conf.d/*.conf

10-auth.conf ,

10-master.conf,

auth-passwdfile.conf.ext,

10-ssl.conf

and 10-logging.conf (all logs are on)

All others, form the 29 configuration files, I haven't touch. It has worked, before I have done the update. What has changed? For what in the *.conf should I locking for?

Thanks a lot.
