Failed to set user and group on file

[harthurd]

Hello!
There is an error message in the logs:
[Fri Nov 24 11:30:20.508777 2023] [auth_gssapi:error] [pid 16564:tid 140529316624128] [client 127.0.0.1:36116] failed to set user (128048423) and group (128100511) on file (/tmp/[email protected])!, referer: https://my.domain.com/login
Tell me, please, why does the module gss-api try to set file permissions for a domain user 128048434 ?
The owner of the directory with the ticket cache is www-data and he can write and read to it.
Thanks!
