KB-8929: Log into Docker container using AD user does not work

Centrify DirectControl ,  

19 July,17 at 10:19 PM

Problem: 
After setting up Centrify Direct Control in a Docker Container (Docker version 1.12.6-28), it is not possible to log in with an AD user. 

Example attempting to log in with user 'cook':
  
$ docker run -it -u cook -v /var/centrifydc:/var/centrifydc mycentos:working  /bin/bash
/usr/bin/docker-current: Error response from daemon: linux spec user: unable to find user cook: no matching entries in passwd file.

Cause:

There is an issue with docker, when it launches /bin/bash, it looks at /etc/passwd itself rather than using getpwnam/getpwuid like when it verifies invoking the user.

Resolution:

Please contact Docker Support to address this issue.
