The bootstrap script can be updated correctly by running `mgr-bootstrap` on top of SUSE Manager Server.

Resolution

Add the following in `/etc/security/access.conf` to grant access to the "tomcat" user:

+:tomcat:ALL

It might be also needed to create a sudoers drop-in file. Add the following to `/etc/sudoers.d/01_tomcat`

tomcat ALL = NOPASSWD: /usr/bin/rhn-bootstrap

Cause

The "tomcat" user is not allowed in `/etc/security/access.conf` file.

Additional Information

An example of `/etc/security/access.conf`
+:user00,user01,user02:ALL
+:user03:LOCAL
-:ALL:ALL
This means:
  • all the users in the first line starting with '+' are allowed in
  • user "user03" is allowed in but only from localhost
  • ALL other users are NOT allowed
