Default JDBC User Store Configuration

The default JDBC user store reads/writes into the internal database of the Carbon server. Internal JDBC user stores can be configured using <PRODUCT_HOME>/repository/conf/user-mgt.xml file's JDBCUserStoreManager configuration section.

The default configuration is shown below. Change the values according to your requirements.

<UserStoreManager class="org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager">
	 <Property name="TenantManager">org.wso2.carbon.user.core.tenant.JDBCTenantManager</Property>
	 <Property name="ReadOnly">false</Property>
	 <Property name="MaxUserNameListLength">100</Property>
	 <Property name="IsEmailUserName">false</Property>
	 <Property name="DomainCalculation">default</Property>
     <Property name="PasswordDigest">SHA-256</Property>
	 <Property name="StoreSaltedPassword">true</Property>
	 <Property name="UserNameUniqueAcrossTenants">false</Property>
	 <Property name="PasswordJavaRegEx">[\S]{5,30}$</Property>
	 <Property name="PasswordJavaScriptRegEx">[\\S]{5,30}</Property>
	 <Property name="UsernameJavaRegEx">^[^~!#$;%^*+={}\\|\\\\&lt;&gt;,\'\"]{3,30}$</Property>
	 <Property name="UsernameJavaScriptRegEx">[\\S]{3,30}</Property>
	 <Property name="RolenameJavaRegEx">^[^~!@#$;%^*+={}\\|\\\\&lt;&gt;,\'\"]{3,30}$</Property>
	 <Property name="RolenameJavaScriptRegEx">[\\S]{3,30}</Property>
	 <Property name="UserRolesCacheEnabled">true</Property>
</UserStoreManager>

The main elements of the above configuration are described below.

Property Name	Description
TenantManager	Includes the location of the tenant manager.
ReadOnly	Indicates whether the user store of this realm operates in the user read only mode or not.
MaxUserNameListLength	Maximum number of users retrieved at once by user real.
IsEmailUserName	Indicates whether Email is used as user name (apply when realm operates in read only mode).
DomainCalculation	Can be either default or custom (apply when realm operates in read only mode).
PasswordDigest	Digesting algorithm of the password. Has values such as PLAIN_TEXT, SHA etc.
StoreSaltedPassword	Indicates whether to salt the password.
UserNameUniqueAcrossTenants	An attribute used for multi-tenancy.
PasswordJavaRegEx	A regular expression to validate passwords. By default, strings having length 5 to 30 non-empty characters are allowed.
PasswordJavaScriptRegEx	The regular expression used by the font-end components for password validation.
UsernameJavaRegEx	A regular expression to validate usernames. By default, strings having length 5 to 30 non-empty characters are allowed.
UsernameJavaScriptRegEx	The regular expression used by the font-end components for username validation.
RolenameJavaRegEx	A regular expression to validate rolenames. By default, strings having length 5 to 30 non-empty characters are allowed.
RolenameJavaScriptRegEx	The regular expression used by the font-end components for rolename validation.
UserRolesCacheEnabled	This is to indicate whether to cache the role list of a user. By default it is 'true'. Set it to 'false' if user-roles are changed by external means and those changes should be instantly reflected in the carbon instance.

In addition to the above properties, set the following also in <PRODUCT_HOME>/repository/conf/user-mgt.xml file.

MultiTenantRealmConfigBuilder property should be set to org.wso2.carbon.user.core.config.multitenancy.SimpleRealmConfigBuilder. For example:
```
<Property name="MultiTenantRealmConfigBuilder">org.wso2.carbon.user.core.config.multitenancy.SimpleRealmConfigBuilder</Property> 
```
This property is described in section Realm Configuration.

Add a property by the name passwordHashMethod to JDBCUserStoreManager default configuration shown above and set the value to SHA or PLAIN_TEXT. For example:

<UserStoreManager class="org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager">
...
    <Property name="passwordHashMethod">SHA</Property>
...
</UserStoreManager>

Go to <PRODUCT_HOME>/repository/conf/tenant-mgt.xml file and comment out the CommonHybridLDAPTenantManager, which is used by default and uncomment JDBCTenantManager. For example:
```
<TenantManager class="org.wso2.carbon.user.core.tenant.JDBCTenantManager"></TenantManager>
```
