How to read operational attributes from ldap server

Question

I have to read operational attributes from the LDAP server (createTimeStamp, entryUUID etc).

I have tried to implement own UserDetailContextMapper but without success.

At the moment my code looks like this

Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth
            .ldapAuthentication()
            .userSearchFilter("uid={0}")
            .groupSearchBase("ou=users")
            .userDetailsContextMapper(userContextMapper())
            .contextSource(contextSource());
}

@Bean
public LdapContextSource contextSource() {
    LdapContextSource contextSource = new LdapContextSource();
    contextSource.setUrl("ldap://ldap.company.pl:389");
    contextSource.setBase("dc=company,dc=com");
    contextSource.afterPropertiesSet();
    return contextSource;
}

@Bean
public UserDetailsContextMapper userContextMapper() {
    return new CustomUserDetailContextMapper();
}

My UserDetailContextMapper implementation:

public class CustomUserDetailContextMapper implements UserDetailsContextMapper {

@Override
public UserDetails mapUserFromContext(DirContextOperations ctx, String username, Collection<?
        extends GrantedAuthority> authorities) {
    AutoUser user = new AutoUser();

    user.setCreateTimeStamp(ctx.getStringAttribute("createTimestamp"));
    user.setUUID(ctx.getStringAttribute("entryUUID"));
    user.setEmail(ctx.getStringAttribute("mail"));
    return user;
}

@Override
public void mapUserToContext(UserDetails user, DirContextAdapter ctx) {
    //default impl
}

}

I've tried Attributes attributes = ctx.getAttributes(username, new String[] {"*", "+"});

in mapUserFromContext() method, but I'm receiving NamingException if i pass username .

I was thinking about implementing ldapTemplate.lookup(), but I'm not really sure where to implement it, I've tried to do userRepo class with ldapTemplate, but I got NameNotFoundException with any DN I pass.

StackTrace for namingException from ctx.getAttributes()

I can retrieve object from LDAP using query like that:

public Object getAll(){
    return ldapTemplate.search(query()
    .where("entryUUID").is("<HasToPassUUIDFromLDAP"), new PersonAttributesMapper());
}

but I need to pass full attribute value, which is not the point since i want to retrieve this value, not the object with this value.

Answer 1

    ctx.getAttributes(username, new String[] {"*", "+"});

1. username - according to the documentation, this should be the DN That's how LDAP knows which record you're pulling data from

2. The second parameter, if you set it to null , it will retrieve all attributes

I believe your error is thrown because you're passing in a username instead of a distinguished name .

    /**
     * Retrieves selected attributes associated with a named object.
     * See {@link #getAttributes(Name, String[])} for details.
     *
     * @param name
     *          The name of the object from which to retrieve attributes
     * @param attrIds
     *          the identifiers of the attributes to retrieve.
     *          null indicates that all attributes should be retrieved;
     *          an empty array indicates that none should be retrieved.
     * @return  the requested attributes; never null
     *
     * @throws  NamingException if a naming exception is encountered
     */
    public Attributes getAttributes(String name, String[] attrIds)
            throws NamingException;
