English Actions
Each of these files serves as a template. A template is a plain text file with optional usage of several operators that can be used to provide some optional profile features.
*{continue if "feature"}*
Immediately stop processing of the file unless "feature" is defined (the rest of the file content will be removed). If "feature" is defined, the whole line with this operator will be removed and the rest of the template will be processed.
*{stop if "feature"}*
Opposite of "continue if". Immediately stop processing of the file if "feature" is defined (the rest of the file content will be removed). If "feature" is not defined, the whole line with this operator will be removed and the rest of the template will be processed.
*{include if "feature"}*
Include the line where this operator is placed only if "feature" is defined.
*{exclude if "feature"}*
Opposite to "include-if". Include the line where this operator is placed only if "feature" is not defined.
*{imply "implied-feature" if "feature"}*
Enable feature "implied-feature" if feature "feature" is enabled. The whole line with this operator is removed, thus it is not possible to add anything else around this operator at the same line.
*{if "feature":true|false}*
If "feature" is defined, replace this operator with string "true", otherwise with string "false".
*{if "feature":true}*
If "feature" is defined, replace this operator with string "true", otherwise with an empty string.
It is also possible to use logical expression in conditional line instead of specifying single feature name. In this case the expression will evaluate to true or false and the conditional operator will act upon the result.
The expression syntax consists of feature names (e.g. _"feature"_) which returns _true_ if the feature is defined or _false_ if it is not defined and from the following logical operators: _and_, _or_ and _not_. The expression may also be enclosed in parentheses and contain multiple subexpressions.
For example:
*{if "feature1" or "feature2":true}*
If "feature1" or "feature2" is defined, replace this operator with string "true", otherwise with an empty string.
*{if not "feature":true|false}*
If "feature" is not defined, replace this operator with string "true", otherwise with string "false".
*{if not "feature":true}*
If "feature" is not defined, replace this operator with string "true", otherwise with an empty string.
*{if "feature1" and ("feature2" or "feature3"):true}*
If "feature1" is defined, and one of "feature2" and "feature3" is defined replace this operator with string "true", otherwise with an empty string.
EXAMPLE
Here is an example of using "if" operator. If "with-sudo" feature is enabled, it will add "sss" to sudoers line.
passwd: sss files
group: sss files
netgroup: sss files
automount: sss files
services: sss files
sudoers: files {if "with-sudo":sss}
Here is an example of "continue-if" and "include-if" operators. The resulting file will be empty unless "with-smartcard" feature is enabled. If it is enabled and also "with-faillock" feature is enabled, it will also enable support for pam_faillock.
{continue if "with-smartcard"}
auth required pam_env.so
auth required pam_faildelay.so delay=2000000
auth required pam_faillock.so preauth silent deny=4 unlock_time=1200 {include if "with-faillock"}
auth [default=1 ignore=ignore success=ok] pam_succeed_if.so uid >= 1000 quiet
auth [default=1 ignore=ignore success=ok] pam_localuser.so
auth sufficient pam_unix.so nullok
auth requisite pam_succeed_if.so uid >= 1000 quiet_success
auth sufficient pam_sss.so forward_pass
auth required pam_faillock.so authfail deny=4 unlock_time=1200 {include if "with-faillock"}
auth required pam_deny.so

It is also possible to use a logical expression in a conditional line instead of specifying a single feature name. Then the expression will evaluate to true or false and the conditional operator will act accordingly.
