my "userPrincipalName":
looks like this:

surname.name@DOMAIN.TLD

maybe this was different because of the version of python used back when the image was built. but as I had to trust my CA-certificate I had to build it myself which leads to an updated system.

[theoneandonly-vector]

I just built it with:
"python:3.6-alpine3.13"
-> same error
"python:3.6-alpine3.12"
-> same

I have the same error. Does anyone solved this issue?

[theoneandonly-vector]

@Widmo
just use this project:
https://github.com/myOmikron/mailcow-ldap-sync

it works perfectly for me.

[Widmo]

Thank You, I will try, but I'm afraid there is no any even simple documentation :)))

[theoneandonly-vector]

have a look at the issues.

[paz]

is there more information on this issue? are you using a windows server or linux ldap backend?

[Widmo]

Windows LDAP backend, this error appears even, when group / OU is empty.

Hi. I've added exception handler in syncer.py to ignore such errors. Try it.
PS. In my syncer.py instead of userPrincipalName I use mail attribute. If it is a problem for you just edit syncer.py (in lines 44 and 47)
