Spring Security LDAP authentication Multiple dn pattern

[Varshini Priya]

We are using spring security & using LDAP to authenticate our web application. In our LDAP configuration, there are multiple userndn patterns available. I would like to know how to configure multiple userdn patterns in the applicationContext-security.xml file. I have the below configuration specified

<b:bean id="ldapProvider"
    class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
    <b:constructor-arg>
        <b:bean
            class="com.intl.set.him.mait.security.CustomLdapAuthenticator">
            <b:constructor-arg ref="ldapContextSource" />
            <b:property name="userDnPatterns" value="cn={0},OU=GEN"/>
            <b:property name= "commonNameQuery" value = "select USER_CN from emt.sec_users1 where user_id=?"/>
            <b:property name="datasource" ref="dataSourceMSSQL"/>  

</b:bean>

When I provide the above configuration in the xml file, users corresponding to Dn pattern for a specific location will only be able to login. I want to know how we can configure multiple userdn patterns in the xml file.

Any help on this is much appreciated. Thanks

Wouldn't you just want to use the ldap user details service instead of a custom provider?

Also, you can create multiple UserDetailsService(s) and add them and authentication will loop through them till one authenticates the user. So each one would have a different dn pattern and work with what you are looking for.
