Try to append the domain to your username when calling sogo-tool (ex: postmaster@example.com).

I run sogo-tool with the backup ALL option. This should take every user that is existent? Otherwise I would need to write an loop and go through all my domains and users individually?

But I tried running it just for one user. I still get the response:

sogo-tool backup /var/vmail/backup/test david@test.de
<0x0x563d33ac5520[SOGoCache]> Cache cleanup interval set every 300.000000 seconds
<0x0x563d33ac5520[SOGoCache]> Using host(s) '127.0.0.1' as server(s)

2019-04-02 20:08:12.495 sogo-tool[30880:30880] Creating NGLdapConnection instance for bindDN 'cn=vmail,dc=v22018112979977771,dc=ultrasrv,dc=de'
2019-04-02 20:08:12.497 sogo-tool[30880:30880] user 'david' unknown

When I log into SOGo with the user everything is working, as well as the backup:

sogo-tool backup /var/vmail/backup/test david@test.de
<0x0x55769876b520[SOGoCache]> Cache cleanup interval set every 300.000000 seconds
<0x0x55769876b520[SOGoCache]> Using host(s) '127.0.0.1' as server(s)

in /var/vmail/backup/test there is the david@test.de file.

Any other idea?

Using sogo-tool and placeholders in your LDAP source is just not tested/working for now and specifying ALL will likely never work with a dynamic configuration (!).

Thanks for the answer. I will write an script to loop through all domains and user then.

Another quick update:

ldapsearch -D "cn=vmail,dc=v22018112979977771,dc=ultrasrv,dc=de" -W -x -LLL 'mail=*' | grep "mail:" | cut -d " " -f 2 | paste -sd " "

gives me basicly an list of all users in the format of user@domain.com.
I tried appending that list of users to sogo-tool but even with correcly specifying the correct mail, sogo-tool still says that there is no user?

It's normal since sogo-tool has not been patched to work with domain placeholders.

Thanks for the information. Is there any chance that there will be a patch in the newer future?

Dear @francis,

We (iRedMail team) sponsored the domain placeholder in LDAP baseDN, can we also have this backup function working?

That would be a charm if the backup works, otherwise the placeholder feature is not really usable in a production system.

Any update so far? I would appreciate to get any information about wether you will fix that bug or not.
I'm planning to use SOGo on a longterm base for a few of my projects.

Thanks in forward.

It will be fixed but you'll need to specify the domain.

hi @francis,

Specifying domain name will bring sysadmin some workload. Is it possible to make it working without specifying the domain name?

Possible solutions:

• Get users from SOGo SQL database directly. If user account exists in LDAP, but no any data in SOGo, we don't need to backup its data (no data at all).
• Add a new parameter, e.g. "backupBaseDN = xxx", used to query all mail users for backup. This dn should not contain any placeholder and the query result should contain all mail users.

This is great news.

@zhb is right, specifying the domain would force us to write additional scripts.
But it would be doable to loop through all domains tho.

Any information on when this will be done?

Thanks in foward!

I pushed a fix.

If you want things to work perfectly you MUST set UIDFieldName to 'mail' - otherwise it makes no sense as the domain name won't extractable dynamically from the database.
