Prevent anonymous bind in LDAP - spring-security

Am developing the spring application with LDAP. Is there is any option to prevent the anonymous bind in LDAP. Am using Apache Directory Studio. Even I am giving the simple bind. Anonymous bind is permitted
Pl. help me to fix this.
Thanks in Advance

Most current LDAP server implementations have an option to disable anonymous binds.
From a LDAP client perspective you can check if the bindDN and password is empty and disallow any such request.
THere is also a "Un-authenticated Bind" term used by some were the bindDN is known but the password is empty which you could also disallow.

ActiveMQ Artemis JMX access

I would like to know if there is a way to access values of MBeans in Apache Artemis. The problem is that MBeans access is protected by role access defined in management.xml. When you are accessing MBeans you should have role required in settings, but from my Java app I cannot apply role when I'm accessing MBeans. Same thing happens when I use VisualVM, I can see list of MBeans but due to access constraint I cannot see value of MBeans.
One workaround is to actually remove <authorization> element from management.xml or to simply add org.apache.activemq.artemis in <whitelist> element.
It would be nice if I could do it via reflection in runtime. I've tried couple of times but didn't have much success. Is there a way to override any of Artemis' properties in runtime and that way make access possible?
MBean access restriction is part of the security of the broker. Having a way to circumvent that security or just disable it at runtime without the proper authentication & authorization would be a significant security hole. If MBean access wasn't restricted then anyone with remote access could shut the broker down or even delete all the messages in your queues.
If you want to access the MBeans without restriction you'll need to change management.xml as you noted.
You could also just submit the proper username & password from your application so that the broker would grant you access.

create a local user in jenkins along side LDAP authentication

The purpose is to create a local user in jenkins(granting admin rights) along side the LDAP group authentication so that this "local" user can perform all admin actions whenever the LDAP authentication is not working.
I can set up active directory user(valid users with a valid id), but i want to explore the possibility of setting up "local" jenkins user
I tried to figure this out through JENKINS JIRA but there is no mention of jenkins local user.
Can anyone help me figure this out.
You can't.
When you activate LDAP authentication, you automatically disable Jenkins' internal user database. Both cannot co-exist.
I agree with the accepted answer in that Jenkins does not currently appear to support the simultaneous use of internal authentication and LDAP authentication.
That said, what I do to work around this is:
Run a local copy (i.e. on the Jenkins system itself) of slapd
Configure Jenkins with LDAP authentication, and point him to both my local LDAP directory and our organization's directory
See screenshots:
By doing so, I'm able to create (within the local LDAP instance) a handful of service accounts, and also utilize my org's LDAP authentication for everything else. (On a side note, I use the "Project-based Matrix Authorization Strategy" to manage authz.)
Setting up a local directory is more effort at the outset, but it solves the problem you are describing -- at least until a better solution is available.
There is an improvement filed here to support local users and LDAP users at the same time: https://issues.jenkins-ci.org/browse/JENKINS-3404
Active Directory Plugin has an option for a fallback user since V2.5

iControl REST Remote Authentication BIG-IP v11.5.1 and LDAP

I am using F5 IControl 11.5.1,i have integrated ldap and working fine but i need to access F5 using icontrol rest service.
is there any rest end point available in 11.5.1?
what are parameters and how to pass for ldap?
iControlRest is available in 11.5.1. It was introduced in 11.4 as an early access feature and fully implemented in 11.5. The documentation for iControlRest can be found here. You can find the endpoints and examples for how to use them there. Here's another link to the PDF of the user manual for the 11.5.0 version.
The format for using iControlRest is https://BIGIP/mgmt/tm/ltm/pool. The endpoints use Basic authentication so you'll need to make sure to that the basic Authorization header. Also, you'll need to use an account that has admin permissions to the box.
There is no way to bypass LDAP/TACACS or remote authentication as of this time in any version. I recently opened a case for the same issue. The service account you use must exist in LDAP or you have to use the "admin" account.
Recently, F5 came up with a concept of Role Based Access Control (RBAC), — create a local user a/c but here you can be able to just add Username and Role. No password entry is available. Make sure you use Username that is not listed in the remote role groups on the remote authentication server (Active Directory - ldap).

How to store spring security session information in redis?

I am using Spring security for Authentication and Authorization in my application. I am using Neo4j database as backend and implemented userDetailsService for authentication.
However, whenever my application restarts, user is forced to login once again.
To overcome this, i am thinking to store session information in redis database and load the data to Spring security Context whenever application gets started.
Kindly pass on if there are any articles and pointers to implement the same.
I am thinking of following implementation for it,
1) For every successful authentication, store user details and session details in redis.
This must be implemented in loadUserByUsername() method of UserDetailsService implementation
2) Remove the data from redis, whenver user logs out, Where can i do this information? Is there any spring security function where i can call this
3) Load all the data from redis to spring security whenever application restarts, again where do i need to write this logic?
Please let me know if i have missed any information.
All you need to do is to implement a
SecurityContextRepository that handles security context storage to reds
Eventually a custom filter that retrieves/ stores session information (GenericFilterBean)
I think it is possible to just give the standard filter a different repository, but I am not sure, I needed my own implementation anyway...
Store session in a redis is out-of the box functionality now

You need to configure remember-me feature of Spring Security.
Remember-me or persistent-login authentication refers to web sites being able to remember the identity of a principal between sessions. This is typically accomplished by sending a cookie to the browser, with the cookie being detected during future sessions and causing automated login to take place. Spring Security provides the necessary hooks for these operations to take place, and has two concrete remember-me implementations. One uses hashing to preserve the security of cookie-based tokens and the other uses a database or other persistent storage mechanism to store the generated tokens.
More information available in Spring Security documentation:
http://static.springsource.org/spring-security/site/docs/3.1.x/reference/remember-me.html
You can use out of box implementations or inject your own (aforementioned redis).
As Luke Taylor said, Tomcat's default action is serialize/deserialize sessions on container restart.
Here
pathname attribute of standard manager is the name of the serialization file. If you dont specify a path name attirbute the default is SESSIONS.SER
If you dont want to have sesssions back when restarted, you need to specify it as empty string value..

Configuring default user in spring security

is there a way to configure spring security to have a default user (with roles and such)? i want to use it for testing purposes in an embedded jetty environment.
i provided an InMemoryUserDetailsService but i am missing the part where i tell spring security to use which user.
thanks for your help
fabian
Do you mean an anonymous user?
If so, try this: http://static.springsource.org/spring-security/site/docs/3.0.x/reference/anonymous.html
("Spring Security's anonymous authentication just gives you a more
convenient way to configure your access-control attributes")
