Multivalued sections

In the "NFS Client settings" Technique, there is a multivalued section with several entries. Here is a partial extract from it, with

  • A multivalued section, named NFS mountpoint, that is multivalued and is a component. The variable reference for this component (the key) is NFS_CLIENT_LOCAL_PATH
  • One SELECT1 field, that will show two radio buttons, Mount and Unmount, with the default value to Mount
  • One INPUT field, named NFS_CLIENT_LOCAL_PATH, that is a text
 <SECTION name="NFS mountpoint" multivalued="true" component="true" componentKey="NFS_CLIENT_LOCAL_PATH">
       <DESCRIPTION>Which operation should be done on this mountpoint</DESCRIPTION>
       <DESCRIPTION>Local path to mount the remote on</DESCRIPTION>

Unique variable across several instance

This variable can have only one value, over all the instances of this Technique, on a node

        <DESCRIPTION>Unique variable</DESCRIPTION>

Password handling

The password type allows to show an input text field whose content will be hashed when the form is submitted so that the password is never store in clear text.

Directive Password Field

Available hash formats

For now, the password field support these hash algorithms :

  • PLAIN : that is not an hash algorithm, it just save the password in plain text, as inputed by the user.
  • MD5, SHA1, SHA256, SHA512 : uses the matching hash algorithm
  • LINUX-SHADOW-MD5, LINUX-SHADOW-SHA256, LINUX-SHADOW-SHA512 : build a string compatible with the Linux /etc/shadow format, as "specified" in http://man7.org/linux/man-pages/man3/crypt.3.html

Technique metatdata content

To configure a password, you must specify two things in the <CONSTRAINT> section of the field:

  • <TYPE>password</TYPE> : use the password type
  • <PASSWORDHASH>comma,separated,list,of,hash</PASSWORDHASH> : specify the list of hash algo from witch the user will be allowed to choose.
  • Available algorithm names are the ones from the section above (case insensitive).
  • Choices are presented in order given by the list, the first being the default one.
  • If the list contains only one algo, the drop down select if change to a phrase saying to the user that the given algo will be used.
  • The list can not be empty. Moreover, if the <MAYBEEMPTY> contraint is set to false, the "None" option is not displayed to the user.

Password field definition example

<SECTION name="Password" component="true" componentKey="USERGROUP_USER_LOGIN">
        <DESCRIPTION>Password for this account</DESCRIPTION>
