Mail stack (mail,SOGo, roundcubemail): Migrate a mail stack and change the base DN

[stephdl]

We need to test the migration of an openldap directory.nh to another base DN set by the sysadmin

For this purpose the test the platform we need to install on NS7 and migrate the whole stack to NS8

nethserver-openldap nethserver-mail-server nethserver-roundcubemail nethserver-sogo

ghcr.io/nethserver/sogo:2.0.4-dev.1 ghcr.io/nethserver/roundcubemail:2.0.5-dev.1 ghcr.io/nethserver/mail:1.4.10-dev.2 testing version of nethserver-ns8-version : http://packages.nethserver.org/nethserver/7.9.2009/testing/x86_64/Packages/nethserver-ns8-migration-1.0.18-1.1.g865021d.ns7.x86_64.rpm

To test the event user-domain-changed and the migration of the base DN to another DN, you have to write to the /usr/share/nethesis/nethserver-ns8-migration/apps/{nethserver-sogo, nethserver-mail, nethserver-roundcubemail}/bind.env the version above and migrate the mail stack to a NS8

• install NS7 with an openldap account provider, mail and sogo
• create some data like users in LDAP, some emails
• install the testing version of nethserver-ns8-migration: yum install http://packages.nethserver.org/nethserver/7.9.2009/testing/x86_64/Packages/nethserver-ns8-migration-1.0.18-1.1.g865021d.ns7.x86_64.rpm
• modify the bind.env to set the version of sogo, mail, roundcubemail this is an example : vim /usr/share/nethesis/nethserver-ns8-migration/apps/nethserver-sogo/bind.env change MODULE_IMAGE_URL="sogo" to MODULE_IMAGE_URL="ghcr.io/nethserver/sogo:2.0.4-dev.1"

case 1

• try to migrate to a base DN that it does not exist (length, characters, ....).
• the validator must stop you

case 2

• create an openldap account provider on the NS8 : sub.domain.com
• migrate the stack to NS8 with the same account provider name sub.domain.com given by the UI
• you must have an error that the account manager exists on the NS8 server

case3

• migrate the mail stack by the UI, set a bind DN like asked by the UI
• once the stack is migrated, using the remote account provider you can use roundcubemail, sogo and mail
• once the test before is good, migrate the account provider
• at the end of the account provider migration, the event user-domain-changed is triggered and all the services (postfix service, dovecot service, sogo pod, roundcubemail pod) will restart (you can see it in journald of NS8)
• once the stack is migrated,do not reconfigure something, just test, you can

1. login to sogo with a user of the LDAP (do not reconfigure something) and send and receive email from sogo to a user of the ldap
2. use the ldap address book of roundcubemail, send and receive email to a user of the LDAP
3. the ldap with the new name is well migrated and usable in NS8 (you can use the user-account-manager with admin permission or with simple user)
