I have set up a Ldap Server somewhere. I can bind to it, can add, modify, delete entry in the database. Now when it come to authentication isnt it as simple as giving the username and password to the server, asking it to search for an entry matching the two? And furthermore, isnt it the 'userPassword' field that contains the password for a user in there?
Now,
I tried to set up splunk to authenticate from my Ldap server, i provided the username and password, but it failed authentication. Isnt it that 'userPassword' field that splunk checks? What should be the possible reason?
LDAP servers are generally not going to allow you to search on the userPassword attribute, for obvious security reasons. (and the password attribute is likely stored in hashed form anyway, so a straight search would not work.)
Instead, the usual way to do LDAP authentication is:
prompt for username & password
Bind to LDAP with your application's account, search for username to get the full distinguished name (dn) of the user's LDAP entry
Make a new LDAP connection, and attempt to bind using the user's dn & password
(If you know how to construct the dn from the username, you can skip step 2, but it's generally a good idea to search first - that way you're less sensitive to things like changes in the OU structure of the LDAP directory)
Typically you would search using the username value provided on uid or cn values within the LDAP Tree.

I have a created a ldap server . I registered some users in that server. For now i am able to login through server using username and password of users from my mac system.But now i want to login through server using mail id and password of users instead of username and password.How to change this setting in mappings of ldap in mac.
Go through this link https://help.apple.com/advancedserveradmin/mac/10.7/#apdB5DE1FD6-4D51-4C20-BB66-982DB85DF258. it helped me a lot. we have to give DN as mail=mailaddress,OU=users,dc=example,dc=com.
and password whatever we configured during server configuration.
I'd add a new Mapping-File to the DirectoryServices as stated in http://support.apple.com/kb/PH9293?viewlocale=en_US&locale=en_US. That way you can map not only the UID or the CN for logging into the machine but also the email-address. That way you will only have to store the email-address in the corresponding field that is also used by the mail server and the possibility that one time something gets mixed up due to incomplete changes is reduced.
On the other hand it might be a lengthy process to get everything right
Update: I've just written a blog-post about mapping LDAP-Attributes to DirectoryService-Attributes. It might be helpfull here: http://andreas.heigl.org/2014/06/05/change-opendirectory-mappings/
I have SugarCRM running and able to log in and out using the super admin account. I created a new user with type Regular User and defined it password because I unchecked the auto generation of password.
Even if I change the password through the database I cannot log in. But, if I changed the the type to Administrator that user can now login. Why is that? I want it to be a Regular User only.

In version 6.5.x I have found that there is a problem with password rules. Perhaps this is the case. Go to config.php and look at passwordsetting array. There is a minpwdlenght and a oneupper. Change 'oneuppper' to 'false' and match minpwdlenght to the lenght you want.
This solved my issue.
I have several windows applications that can be access through an SQL account. I need to validate the user password against Local Security Policy of the Server without modfiying the password itself.
What I require is an SQL statement that return a boolean value whether or not the password is according to the server policy or not.
Is it something possible?
Based on the extra information in your comment, it seems that you want to validate existing SQL login passwords against the Windows password policy, but without making any changes to the logins.
This is probably not possible because there is no way to retrieve a SQL login password, so there is no way to validate them yourself programmatically. However, according to the documentation, the check is on by default, so it's possible that all your passwords are already compliant with the OS security policy, unless you've deliberately set this off and then on for some logins.
If you need to ensure that all login passwords comply with the policy, the best way to make sure is to set the check on for all logins (if it isn't already) and force a password change. Even better, stop using SQL logins and use Windows logins instead, although I know that isn't possible in every situation.
I'm running into a problem using LDAP to authenticate logins.
We are using a Novell edirectory for authentication of other applications like Jira. ( Jira works perfect ).
I have this application that allow these basic LDAP configurations:
My problem is, when I try to log in, it takes my username XXXXXXXX and pre-pends it to the search base as uid. So it tries to log me in as :
uid=XXXXXXXX,ou=people,o=mycompany
Which would work on our Sun LDAP server, but doesn't work on our Novell edirectory LDAP server. edirectory only works when I try to log in as the distinguished name :
cn=XXXXXXXX,ou=people,o=mycompany
Why does edirectory behave like this?
Is it config that we have specified or does edirectory always use cn as distinguished name?
Thanks
I suggest that is is the application that is 'behaving like this', not edirectory. Obviously your edirectoryis structured differently from your Sun LDAP server, yet the application is treating them both the same. LDAP servers only execute queries, they don't construct them. The application does that.
The naming attribute is up to the person making the object. However by default most eDirectory tools set it as cn=. If you want, you can create objects as uid= in your eDirectory. It would be hard to convert existing users.
Many LDAP tools that make this assumption will allow you to specify what the naming attribute might be.
Your app is making a bad assumption.
You can add a UID value on each object, the same as the CN, but that would not help since it is not then a naming attribute.
In other words, if the application was doing a query for (uid=XXXXXXXX) then adding a uid value that matches CN would help.
If however it is doing a bind as a specific user, as uid=XXXXXXXX,ou=users,o=mycompany that won't help.
I'm interested in how other people code this because I'm either not understanding it properly or I'm missing something or perhaps even I'm doing it right!
First of all, this is NOT an Active Directory instance of LDAP its OpenDS which other than some syntactical differences shouldn't much matter.
So assume I have my tree structure setup something like this:
-dc=somedomain,dc=com
-uid=rootuser
-ou=Group1
-uid=username1
-uid=username2
-ou=Group2
-uid=username3
-uid=username4
In order to authenticate as the 'rootuser' I would need to pass the fully qualified Username when I create my System.DirectoryServices.DirectoryEntry object, in this case:
uid=rootuser,dc=somedomain,dc=com
but for any other user in the tree I have to know in advance what LDAP path to append to the username to have them authenticate thru. So for example this will fail:
uid=username1,dc=somedomain,dc=com
but this will work:
uid=username1,dc=somedomain,dc=com,ou=Group1
So my question is how do you handle this when you don't know at login time what specific group a user belongs to to build that path? The only way I can figure to do it is to make the initial call as 'rootuser' so I have access to the entire tree then use System.DirectoryServices.DirectorySearcher to scan it for that particular user (i.e. username1)
using (DirectorySearcher searcher = GetDirectorySearcher()) {
searcher.Filter = "(&(objectClass=person)(uid=" + userName+ "))";
SearchResult result = searcher.FindOne();
return result.GetDirectoryEntry().Path;
}
at that point I have the path for the user I want to login and I can proceed with the actual auth. Am I way off base here or is this generally how it is done?
thanks!
You build a search filter on attributes that are unique to the user, e.g. screen-name, e-mail. Make sure LDAP is configured to ensure they are unique. Then you find the corresponding entry if any, get the DN, and rebind as that user with the appropriate password. If there was no such entry you react accordingly.
You don't say what language you are using, but in JNDI that means setting the DN as the security principal, the password as the credentials, and calling LdapContext.reconnect().
SASL supports the notion of using a username to authenticate. Your directory server administrator may be able to configure the directory server to map distinguished names to identities. Given the correct mapping it is possible for a client to authenticate without knowing the distinguished name. Professional-quality directory servers support a number of different mapping mechanisms such as direct mapping, exact match, regular expression, or a custom identity mapper.
