Configuring a Read-only LDAP User Store
- Former user (Deleted)
Before you begin!
Please read following topics:
Read-only LDAP user store manager is configured with org.wso2.carbon.user.core.ldap.ReadOnlyLDAPUserStoreManager user store manager class. This user store manager is only capable of reading values for user store and not allowed to update the entries.
In this page, you can find information on:
Properties used in Read-only LDAP userstore manager
| Property Name | Display Name | Description |
|---|---|---|
| DomainName | Domain Name | Unique name to identify the user store. This should only be configured for secondary user store. |
| ConnectionURL | Connection URL | Connection URL to the user store server. In the case of default LDAP in Carbon, the port is specified in the carbon.xml file, and a reference to that port is included in this configuration. Sample values: |
| ConnectionName | Connection Name | The username used to connect to the user store and perform various operations. This user does not need to be an administrator in the user store or have an administrator role in the WSO2 product that you are using, but this user MUST have permissions to read the user list and users' attributes and to perform search operations on the user store. The value you specify is used as the DN (Distinguish Name) attribute of the user who has sufficient permissions to perform operations on users and roles in LDAP This property is mandatory. |
| ConnectionPassword | Connection Password | Password for the ConnectionName user. |
| UserSearchBase | User Search Based | DN of the context or object under which the user entries are stored in the user store. When the user store searches for users, it will start from this location of the directory Sample values: ou=Users,dc=wso2,dc=org |
| UserEntryObjectClass | User Entry Object Class | Object class used to construct user entries. Default: wso2Person ( Is a custom object class defined in WSO2 products) |
| UserNameAttribute | Username Attribute | The attribute used for uniquely identifying a user entry. Users can be authenticated using their email address, UID, etc. The name of the attribute is considered as the username. Sample values: uid |
| UserNameSearchFilter | User Search Filter | Filtering criteria used to search for a particular user entry. Sample values: (&(objectClass=person)(uid=?)) |
| UserNameListFilter | User List Filter | Filtering criteria for searching user entries in the user store. This query or filter is used when doing search operations on users with different search attributes. Sample values: (objectClass=person) In this case, the search operation only provides the objects created from the person object class. |
| UserDNPattern | User DN Pattern | The pattern for the user's DN, which can be defined to improve the search. When there are many user entries in the LDAP user store, defining a UserDNPattern provides more impact on performances as the LDAP does not have to travel through the entire tree to find users. Sample values: uid={0},ou=Users,dc=wso2,dc=org |
| DisplayNameAttribute | Display name attribute | This is an optional property. The Display Name Attribute is the name by which users will be listed when you list users in the management console. |
| ReadGroups | Read Groups | When WriteGroups is set to falses, this Indicates whether groups should be read from the user store. If this is disabled by setting it to false, none of the groups in the user store can be read, and the following group configurations are NOT mandatory: GroupSearchBase, GroupNameListFilter, or GroupNameAttribute. Possible values: true: Read groups from user store false: Don’t read groups from user store |
| WriteGroups | Write Groups | Indicates whether groups should be write to the user store. Possible values: true: Write groups to user store false: Do not write groups to user store, so only internal roles can be created. Depend on the value of ReadGroups property, it will read existing groups from user store or not |
| GroupSearchBase | Group Search Base | DN of the context or object under which the group entries are stored in the user store. When the user store searches for groups, it will start from this location of the directory Sample values: ou=Groups,dc=wso2,dc=org |
| GroupEntryObjectClass | Group Entry Object Class | Object class used to construct group entries. Sample values: groupOfNames |
| GroupNameAttribute | Group Name Attribute | Attribute used for uniquely identifying a group entry. This attribute is to be treated as the group name. |
| GroupNameSearchFilter | Group Search Filter | Filtering criteria used to search for a particular group entry. Sample values: (&(objectClass=groupOfNames)(cn=?)) |
| GroupNameListFilter | Group List Filter | Filtering criteria for searching group entries in the user store. This query or filter is used when doing search operations on groups with different search attributes. Sample values: ((objectClass=groupOfNames)) In this case, the search operation only provides the objects created from the groupOfName object class. |
| RoleDNPattern | Role DN Pattern | The pattern for the group's DN, which can be defined to improve the search. When there are many group entries in the LDAP user store, defining a RoleDNPattern provides more impact on performances as the LDAP does not have to traverse through the entire tree to findgroup. Sample values: cn={0},ou=Groups,dc=wso2,dc=org |
| MembershipAttribute | Membership Attribute | Defines the attribute that contains the distinguished names (DN) of user objects that are in a group. Possible values: member |
| MemberOfAttribute | Member Of Attribute | Define the attribute that contains the distinguished names (DN ) of group objects that user is assigned to. Possible values: memberOf |
| BackLinksEnabled | Enable Back Links | Defines whether the backlink support is enabled. If you are using MemberOfAttribute attributes this should be set to 'true'. |
| UsernameJavaRegEx | Username RegEx (Java) | The regular expression used by the back-end components for username validation. By default, strings with non-empty characters have a length of 3 to 30 allowed. You can provide ranges of alphabets, numbers and also ranges of ASCII values in the RegEx properties. Default: [a-zA-Z0-9._-|//]{3,30}$ |
| UsernameJavaScriptRegEx | Username RegEx (Javascript) | The regular expression used by the front-end components for username validation. Default: ^[\S]{3,30}$ |
| UsernameJavaRegExViolationErrorMsg | Username RegEx Violation Error Message | Error message when the Username is not matched with UsernameJavaRegEx |
| PasswordJavaRegEx | Password RegEx (Java) | The regular expression used by the back-end components for password validation. By default, strings with non-empty characters have a length of 5 to 30 allowed. You can provide ranges of alphabets, numbers and also ranges of ASCII values in the RegEx properties. Default: ^[\S]{5,30}$ |
| PasswordJavaScriptRegEx | Password RegEx (Javascript) | The regular expression used by the front-end components for password validation. Default: ^[\S]{5,30}$ |
| PasswordJavaRegExViolationErrorMsg | Password RegEx Violation Error Message | Error message when the Password is not matched with passwordJavaRegEx |
| RolenameJavaRegEx | Role Name RegEx (Java) | The regular expression used by the back-end components for role name validation. By default, strings with non-empty characters have a length of 3 to 30 allowed. You can provide ranges of alphabets, numbers and also ranges of ASCII values in the RegEx properties. Default: [a-zA-Z0-9._-|//]{3,30}$ |
| PasswordJavaScriptRegEx | Password RegEx (Javascript) | The regular expression used by the front-end components for password validation. Default: ^[\S]{5,30}$ |
| SCIMEnabled | Enable SCIM | This is to configure whether user store is supported for SCIM provisioning. Possible values: True : User store support for SCIM provisioning. False: User does not store support for SCIM provisioning. |
| BulkImportSupported | Bulk Import Support | Defines whether the user store support for bulk user import operation |
| EmptyRolesAllowed | Allow Empty Roles | Specifies whether the underlying user store allows empty groups to be created. In the case of LDAP in Carbon, the schema is modified such that empty groups are allowed to be created. Usually, LDAP servers do not allow you to create empty groups. |
| PasswordHashMethod | Password Hashing Algorithm | Specifies the Password Hashing Algorithm used the hash the password before storing in the user store. If you just configure as SHA, It is considered as SHA-1, It is always better to configure algorithm with higher bit value as digest bit size would be increased. |
| MultiAttributeSeparator | Multiple Attribute Separator | This property is used to define a character to separate multiple attributes. This ensures that it will not appear as part of a claim value. Normally “,” is used to separate multiple attributes, but you can define ",,," or "..." or a similar character sequence Default: “,” |
| MaxUserNameListLength | Maximum User List Length | Controls the number of users listed in the user store of a WSO2 product. This is useful when you have a large number of users and don't want to list them all. Setting this property to 0 displays all users. Default: 100 In some user stores, there are policies to limit the number of records that can be returned from the query. Setting the value 0 it will list the maximum results returned by the user store. If you need to increase that you need to set it in the user store level. Eg : Active directory has the MaxPageSize property with the default value 1000. |
| MaxRoleNameListLength | Maximum Role List Length | Controls the number of roles listed in the user store of a WSO2 product. This is useful when you have a large number of roles and don't want to list them all. Setting this property to 0 displays all roles. Eg: Active directory has the MaxPageSize property with the default value 1000. |
| kdcEnabled | Enable KDC | If your user store is capable of acting as a Kerberos, Key Distribution Center (KDC) and if you like to enable it, set this property to true. Default: false |
| UserRolesCacheEnabled | Enable User Role Cache | This is to indicate whether to cache the role list of a user. Default: true Possible values: false: Set it to false if the user roles are changed by external means and those changes should be instantly reflected in the Carbon instance. |
| ConnectionPoolingEnabled | Enable LDAP Connection Pooling | Define whether LDAP connection pooling is enabled Possible values: True: Enable connection pooling. Enabling it will improve the performance False: Disable connection pooling. |
| LDAPConnectionTimeout | LDAP Connection Timeout | Timeout in making the initial LDAP connection. This is configured in milliseconds. Default: 5000 |
| ReadTimeout | LDAP Read Timeout | The value of this property is the read timeout in milliseconds for LDAP operations. If the LDAP provider cannot get a LDAP response within that period, it aborts the read attempt. The integer should be greater than zero. An integer less than or equal to zero means no read timeout is specified which is equivalent to waiting for the response infinitely until it is received. Default: 5000 |
| RetryAttempts | Retry Attempts | Retry the authentication request if a timeout happened Default: 0 |
| CountRetrieverClass | Count Implementation | This define the user / role count retriever implementation class (Only supported for ) Possible values: JDBC : org.wso2.carbon.identity.user.store.count.jdbc.JDBCUserStoreCountRetriever |
| java.naming.ldap.attributes.binary | LDAP binary attributes | Set the attribute that need to store in the binary format. The value of this property is a string of space-separated attribute name Sample values: objectGUID |
| MembershipAttributeRange | Membership Attribute Range | This is to define the maximum users of role returned by the LDAP/AD user store. This does not depend on the max page size of the user store. Default: 1500 |
