Environment

Situation

When PAM is enabled on top of SUSE Manager Server.
# cat /etc/pam.d/susemanager
#%PAM-1.0
auth     include        common-auth
account  include        common-account
password include        common-password
session  include        common-session

# cat /etc/rhn/rhn.conf
pam_auth_service = susemanager
An error message can occur when bootstrap script is updated using web-UI. Following messages can be seen in:

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
