Zammad updated a user

[Mr_P]

• Used Zammad version: 3.1.x
• Used Zammad installation source: package
• Operating system: CentOS 7
• Browser + version: MF 68esr

Expected behavior:

Silence

Actual behavior:

Zammad replaces for inexplicable reasons two users over and over again, several times a day. The users are connected via LDAP and do not bring any errors. Start day is probably the 04.10.19 and only for this user… Can anyone tell me why?

Thanks a lot!
Daniel.

I looked on the DC and found that Sybille had entered the email from Mirko… But the mail address wasn’t supposed to trigger a user change, was it?

After changing the mail address zammad creates a new user “Sybille”… Is the address used as unique?

[MrGeneration]

mail addresses and logins must be unique within Zammad.
Normally in LDAP terms we remember the users UID.

This allows us to track use renames (even with mail address and login change)*.

* this does not work natively with other LDAPs than AD.
