Summary: Add the ability to append a random value to values in
LDAP attributes when generating principals in Active Directory
Key: AMBARI-9209
URL: https://issues.apache.org/jira/browse/AMBARI-9209
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Robert Levas
Assignee: Robert Levas
Fix For: 2.0.0
Add ability to append a random value to values in LDAP attributes when
generating principals in Active Directory.
For example the {{cn}} and {{sAMAccountName}} attributes must be unique. In
some caes the {{cn}} is not allowed to have {{/}} characters and in all cases
the {{sAMAccountName}} is not allow to have {{/}} characters. Therefore to
generate values for these attributes, the _instance_ part of the principal
needs to be stripped off and a random string needs to be appended.
This can be seen where the principal is
{{nn/[email protected]}}. The {{cn}} would typically be
{{nn/c6501.ambari.apache.org}}. Providing for a random string would allow the
{{cn}} value to be something like {{nn-ythnskdtarsjko5fsdfdsb}}. Since the
{{sAMAccountName}} can be at most 20 characters, it would be
{{nn-ythnskdtarsjko5fs}}.
Since the generation of the attributes and values is done using a Velocity
template, this random string will need to be generated and stored in the
Velocity engine context before processing the template.
