Hi all
We are in process from migrating from Zimbra to Grummunio.
Using 2026.06.1 appliance.
We configured LDAP options via cli “grommunio-admin ldap configure” to copy the users from various domains hosted on the Zimbra server .
This is the configuration we are trying to use.
+++++++++++++++++++++++++++++++++++++++++++++++++++++
Username for access [uid=zimbra,cn=admins,cn=zimbra]:
Password for access [***]:
Use StartTLS connection [n]:
Checking connectivity...success!
Search base for user lookup/searches [ou=people,dc=xyz,dc=co,dc=mz]:
Choose a template:
0: No template
1: ActiveDirectory
2: OpenLDAP
3: Univention
4: 389ds
Apply default template parameters? [y/N]: n
Attribute containing unique object ID [entryUUID]:
Attribute containing e-mail address of a user [mail]:

Attribute containing alternative e-mail addresses [zimbraMailAlias]:
Default storage quota for imported users (0=unlimited) [0]:

Enter custom mapping ('<ldap-attr> <user-prop>', space separated, one per line, Ctrl-D to finish):

[Done]
E-Mail address attribute of the group [mail]:
Filter expression for groups [(objectClass=zimbraDistributionList)]:

Attribute containing the groups a user is member of [uid]:
Disable LDAP system settings [n]:
Choose an authmgr global system authentication backend:

2: always_ldap
Checking new configuration...
Configuration successful.
Configuration saved

When I try to import a user from LDAP, I get
owa:/var/log # grommunio-admin ldap downsync "boris.wiethoff@xyz.co.mz"
Skipping 'boris.wiethoff@xyz.co.mz': invalid domain
0 synchronized, 1 failed
owa:/var/log #
Of course I created first the domain in the grommunio admin gui.
grommunio-admin ldap dump
grommunio-admin ldap search
Works perfectly.
I think, I am not the first one to migrate from Zimbra to Grommunio.
Recommendation to solve this can be done in English or German Language .
Thank You
Boris
