10.1. List of Global Functions

10.2. Functions

10.2.1. $error = UserAdd ($config_hash, $data_hash)

Creates new user. User attributes are described in $data_hash, $config_hash describes special configuration data.

Example 304. 

    Possible parameters for $config hash:

    "type"      Type of user (string). Possible values:
                "local","system","ldap","nis". ("nis" is not available
                for adding)


    Specific parameters of $config hash, related to LDAP users (all keys
    are optional, there should exist reasonable default values based on
    current LDAP configuration):

    "bind_dn"   
                DN of LDAP administrator, used to bind to LDAP server
                (string)
                
    "bind_pw"   
                Password for LDAP administrator (string)
                
    "anonymous_bind"
    
                If this key is present, there will be done created an
                anonymous connection to LDAP server (if it is allowed).
                
    "member_attribute"
                Name of LDAP attribute, defining the membership in LDAP
                groups (possible values: "member", "uniquemember"). The
                default value is in /etc/ldap.conf (nss_map_attribute).

    "user_attributes"
                List of attributes to be returned by an LDAP search for
                user (list of strings). If empty, all non-empty
                attributes will be returned as a result of search.

    "user_filter"
                Filter for restricting LDAP searches (string).
                The default value is stored as "susesearchfilter" in 
                LDAP configuration.

    "user_base"
                DN of LDAP base where the users are stored (string). By
                default, the value of "susedefaultbase" stored in LDAP
                configuration is used.

    "user_scope"
                The scope used for LDAP searches for users. Possible
                values are 0 (base), 1(one), 2(sub). Default is 2.
    
    "plugins"
                List of plugins which should be applied for user
                (list of strings). General plugin for LDAP users,
                ("UsersPluginLDAPAll") is always available, others are
                part of modules which has to be installed before their
                usage (yast2-samba-server, yast2-mail-server).

    "user_plugins"
                Same as "plugins".

    Values mentioned above are common for all $config hashes in the
    functions for handling user. Additionally, there is a special value
    which is defined only for UserAdd:

    "create_home"
                If this is set to 0, the home directory for new user
                won't be created.
                


    Possible parameters for $data hash:

    "uid"               Login name
    "cn"                Full name
    "userpassword"      User's password
    "homedirectory"     Users's home directory
    "loginshell"        User's login shell
    "gidnumber"         GID of user's default group
    "grouplist"         Hash (of type { <group_name> => 1 }) with groups
                        this user should be member of.
    "shadowinactive"    Days after password expires that account is disabled
    "shadowexpire"      Days since Jan 1, 1970 that account is disabled
    "shadowwarning"     Days before password is to expire that user is warned
    "shadowmin"         Days before password may be changed
    "shadowmax"         Days after which password must be changed
    "shadowflag"        (last value at line in /etc/shadow)
    "shadowlastchange"  Days since Jan 1, 1970 that password was last changed

    <ldap_attribute>    For LDAP users, any attribute supported by
                        users's object class can be here.

Example 305. 

  my $config    = { "type"              => "ldap",
                    "plugins"           => [ "UsersPluginLDAPAll" ],
                    "bind_dn"           => "uid=admin,dc=example,dc=com",
  };
  my $data      = { "uid"               => "ll",
                    "uidnumber"         => 1111,
                    "userpassword"      => "qqqqq"

                    "description"       => [ "first", "second" ],
  };
  # create new LDAP user
  my $error     = UserAdd ($config, $data);

  # create new local user 'hh'; use all available defaults
  UserAdd ({}, { "uid"  => "hh" });

Example 306. 

  You can see on example that LDAP attributes could be passed either
  as list of value or as strings, which is just the same case as a list
  with one value.
 

10.2.2. $error = UserModify ($config_hash, $data_hash)

Modifies existing user. User attributes which should be changed are described in $data_hash, $config_hash describes special configuration data, especially user identification.

Example 307. 

    Special values for $config hash: additinally to the values always
    available (see L<UserAdd>), $config must contains one of the key
    used to identify the user which should be modified:

    "dn"        Distinguished name (DN) - only for LDAP user
    "uid"       User name (which is value of "uid" for LDAP user)
    "uidnumber" UID number ("uidnumber" value for LDAP user)

    For values in $data hash, see L<UserAdd>.

Example 308. 

  my $config    = { "type"              => "ldap",

  };
  my $data      = { "userpassword"      => "wwwww"
  };
  # changes a password of LDAP user (identified with id)
  my $error     = UserModify ($config, $data);

  # change GID value of local user (identified with name)
  $error        = UserModify ({ "uid" => "hh" }, { "gidnumber" => 5555 });

10.2.3. $error UserFeatureAdd ($config_hash);

Adds a new feature (plugin) to the given user.

Example 309. 

    $config hash can contain data always available (see L<UserAdd>)
    and the data used for user identification (see L<UserModify>).

                        "UsersPluginSambaAccount",
                        "UsersPluginMail"
                    ],
                    "uid"               => "ll"
  };

                    "bind_dn"           => "uid=admin,dc=example,dc=com",
                    "group_base"        => "ou=groups,dc=example,dc=com"
  };
  my $data      = { "gidnumber"         => 5555,
                    "cn"                => "lgroup",
                    "member"            => {

                        "uid=ll,ou=people,dc=example,dc=com"    => 1
                    }
  };
  # create new LDAP group

  my $error     = GroupAdd ($config, $data);

  # create new system group 
  GroupAdd ({ "type" => "system" }, {
        "cn"            => "ggg",
        "userlist"      => {
            "root"      => 1,
            "hh"        => 1
        }
  );

10.2.11. $error GroupModify ($config_hash, $data_hash);

Modifies existing group. Group attributes which should be changed are described in $data_hash, $config_hash describes special configuration data, especially group identification.

Example 325. 

    For general values of $config hash, see L<GroupAdd>.
    Additinally, $config must contain one of the key used to identify
    the group which should be modified:

    "dn"        Distingueshed name (only for of LDAP group)
    "cn"        Group name (or value of "cn" attribute for LDAP group).
    "gidnumber" GID number (value of "gidnumber" for LDAP group).

Example 326. 

  # change GID value of local group (identified with name)
  my $error     = GroupModify ({ "cn" => "users" }, { "gidnumber" => 101 });

  my $config    = { "type"              => "ldap",
                    "gidnumber"         => 5555
  };
  my $data      = { "member"            => [
                        "uid=test,ou=people,dc=example,dc=com",
                        "uid=ll,ou=people,dc=example,dc=com",
                        "uid=admin,dc=example,dc=com"
                    ]
  };
  # changes a member attribute of LDAP group (identified with id)
  $error        = GroupModify ($config, $data);

    

Example 327. 

  You can see on example that "member" attribute could be passed either
  as an array (which could one expect for LDAP attribute) or as hash,
  (which is used by YaST for internal representation) as shown in example
  for GroupAdd () function. YaST always takes care of it and does the
  necessary conversions.

10.2.12. $error GroupMemberAdd ($config_hash, $user_hash);

Adds a new member to the given group. User is described in $user_hash, group identification is passwd in $config_hash. User must exist.

Example 328. 

    For general values of $config hash, see L<GroupAdd>.
    For parameters necessary to identify the group, see L<GroupModify>.
    $user_hash must include the information necessary to identify the
    user. This has to be one of these keys:

    "dn"        Distinguished name (DN) [only for LDAP users]
    "uid"       User name (which is "uid" attribute for LDAP user)
    "uidnumber" UID (which is "uidnumber" attribute for LDAP user)

Example 329. 

  my $config    = { "type"              => "ldap",
                    "bind_dn"           => "uid=admin,dc=example,dc=com",
                    "gidnumber"         => 5555
  };
  my $user      = { "uid"               => "my_user" }
  };

  my $error     = GroupMemberAdd ($config, $user);

10.2.13. $error GroupMemberDelete ($config_hash, $user_hash);

Deletes a member from the group.

Example 330. 

    For general values of $config hash, see L<GroupAdd>.
    For parameters necessary to identify the group, see L<GroupModify>.
    $user_hash must include the information necessary to identify the
    user - see L<GroupMemberAdd>

Example 331. 

  my $config    = { "type"              => "ldap",
                    "dn"                => "cn=lgroup,dc=example,dc=com"
  };
  my $user      = { "uidnumber"         => 1000 }

  # removes user with given uidnumber from group with given DN
  my $error     = GroupMemberDelete ($config, $user);

10.2.14. $error GroupDelete ($config_hash);

Deletes existing group. Identification of group is stored in $config_hash.

Example 332. 

    For general values of $config hash, see L<GroupAdd>.
    For parameters necessary to identify the group, see L<GroupModify>.

 

Example 333. 

  my $config    = { "type"              => "local",
                    "uid"               => "users"
  };
  my $error     = GroupDelete ($config);

10.2.15. $data_hash GroupGet ($config_hash);

Returns a map describing selected group.

Example 334. 

    For general values of $config hash, see L<GroupAdd>.
    For parameters necessary to identify the group, see L<GroupModify>.

 

Example 335. 

  my $config    = { "type"              => "ldap",
                    "group_attributes"  => [ "cn", "gidnumber", "member" ],
                    "gidnumber"         => 500
  };
  # searches for LDAP group with gidnumber 500 and returns the hash
  # with given attributes
  my $group     = GroupGet ($config);

10.2.16. $groups_hash GroupsGet ($config_hash);

Returns a hash describing the set of groups. By default, the hash is indexed by GID number, unless statet otherwise in $config_hash.

Example 336. 

    For general values of $config hash, see L<GroupAdd>.
    Additionally, there is a special key

    "index"     The name of the key, which should be used as a index
                in the return hash (default value is "gidnumber").

Example 337. 

  # searches for LDAP groups in default base and returns the hash
  # indexed by GID's with the hash values containing groups with all
  # non-empty attributes
  my $groups    = GroupsGet ({ "type" => "ldap" });

  # returns hash with all NIS groups
  $groups       = GroupsGet ({ "type" => "nis" });

10.2.17. $groups_hash GroupsGetByUser ($config_hash, $user_hash);

Returns a hash describing the set of groups. By default, the hash is indexed by GID number, unless stated differently in $config_hash.

Example 338. 

    For general values of $config hash, see L<GroupAdd>.
    $user_hash must include the information necessary to identify the
    user - see L<GroupMemberAdd>.
    Additionally, there is a special key

    "index"     The name of the key, which should be used as a index
                in the return hash.

Example 339. 

  my $config    = { "type"      => "ldap",
                    "index"     => "dn"
                    "group_scope"       => YaST::YCP::Integer (2),
  };
  my $user      = { "dn"        => "uid=ll,ou=people,dc=example,dc=com" };

  # searches for LDAP groups in default base and returns the hash
  # indexed by DN's with the hash values containing groups with all
  # non-empty attributes
  my $groups    = GroupsGetByUser ($config, $user);
