We did it. So it was what we suspected the other day .. we just took the part of code to encrypt password which was used in Creating users application in LDAP, ans do we made a single jar of it, and implemented it with this code in application context file :
<bean id="ldapAuthenticationProvider" class="org.springframework.security.providers.ldap.LdapAuthenticationProvider">
<constructor-arg>
<bean class="org.springframework.security.providers.ldap.authenticator.PasswordComparisonAuthenticator">
<constructor-arg><ref local="ldapContextSource"/></constructor-arg>
<property name="userSearch" ref="userSearch"/>
<property name="passwordEncoder" ref="OurPasswordEncoder"/>
</bean>
</constructor-arg>
<constructor-arg>
<bean class="org.springframework.security.ldap.populator.DefaultLdapAuthoritiesPopulator">
<constructor-arg index="0"><ref local="ldapContextSource"/></constructor-arg>
<constructor-arg index="1"><value></value></constructor-arg>
<property name="groupRoleAttribute" value="title"/>
<property name="groupSearchFilter" value="(cn={1})"/>
<property name="searchSubtree" value="true"/>
<!-- Can setup additional external default roles here <property name="defaultRole" value="LDAP"/> -->
</bean>
</constructor-arg>
</bean>
<bean class="our.jasper.auth.encoding.JasperPasswordEncoder" id="OurPasswordEncoder"/>
