* TUserManager class |
23
|
|
|
* |
24
|
|
|
* TUserManager manages a static list of users {@link TUser}. |
25
|
|
|
* The user information is specified via module configuration using the following XML syntax, |
26
|
|
|
* <code> |
27
|
|
|
* <module id="users" class="System.Security.TUserManager" PasswordMode="Clear"> |
28
|
|
|
* <user name="Joe" password="demo" /> |
29
|
|
|
* <user name="John" password="demo" /> |
30
|
|
|
* <role name="Administrator" users="John" /> |
31
|
|
|
* <role name="Writer" users="Joe,John" /> |
32
|
|
|
* </module> |
33
|
|
|
* </code> |
34
|
|
|
* |
35
|
|
|
* PHP configuration style: |
36
|
|
|
* <code> |
37
|
|
|
* array( |
38
|
|
|
* 'users' => array( |
39
|
|
|
* 'class' => 'System.Security.TUserManager', |
40
|
|
|
* 'properties' => array( |
41
|
|
|
* 'PasswordMode' => 'Clear', |
42
|
|
|
* ), |
43
|
|
|
* 'users' => array( |
44
|
|
|
* array('name'=>'Joe','password'=>'demo'), |
45
|
|
|
* array('name'=>'John','password'=>'demo'), |
46
|
|
|

47
|
|
|
* 'roles' => array( |
48
|
|
|
* array('name'=>'Administrator','users'=>'John'), |
49
|
|
|
* array('name'=>'Writer','users'=>'Joe,John'), |
50
|
|
|
* ), |
51
|
|
|
* ), |
52
|
|
|
* ) |
53
|
|
|
* </code> |
54
|
|
|
* |
55
|
|
|
* In addition, user information can also be loaded from an external file |
56
|
|
|
* specified by {@link setUserFile UserFile} property. Note, the property |
57
|
|
|
* only accepts a file path in namespace format. The user file format is |
58
|
|
|
* similar to the above sample. |
59
|
|
|
* |
60
|
|
|
* The user passwords may be specified as clear text, SH1 or MD5 hashed by setting |
61
|
|
|
* {@link setPasswordMode PasswordMode} as <b>Clear</b>, <b>SHA1</b> or <b>MD5</b>. |
62
|
|
|
* The default name for a guest user is <b>Guest</b>. It may be changed |
63
|
|
|
* by setting {@link setGuestName GuestName} property. |
64
|
|
|
* |
65
|
|
|
* TUserManager may be used together with {@link TAuthManager} which manages |
66
|
|
|
* how users are authenticated and authorized in a Prado application. |

The issue could also be caused by a filter entry in the build configuration. If the path has been excluded in your configuration, e.g.
excluded_paths: ["lib/*"]
, you can move it to the dependency path list as follows:For further information see https://scrutinizer-ci.com/docs/tools/php/php-scrutinizer/#list-dependency-paths
