We handle the issue...by not using the newest alfresco We don't have any problems with clean alfresco and 201901 with same configuration. We were testing this in simple fashion, just simply changing .env file for docker-compose and docker files. We not changing anything in configuration, only changing version for alfresco repository and alfresco share.
Yep I saw that. I can't find any mistakes and we have working conf with SSO with nginx, kerberos, ad on alfresco 2019.01. I don't think only we have a problem, becouse we have same config working 2019.01-ga. Base on clean alfresco. So our .env file now looks like that.
If we switch config to newest:
We will have 500 for each post request after login to alfresco. In 2019.01 we don't have this problem. Same configuration only change of .env.
Don't get me wrong I would love to use 2019.11, but for now we upgraded only to 2019.01 becouse of this (we were upgrading alfresco from 201701-ga).
