Wanna retreive emailId using the windows login user name from ldap active directory.

[harishpatarla]

Hi,

I am able to connect to my ldap server but after connecting i get an exception when i try n search for a user.

     SearchControls constraints = new SearchControls();

                constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
                String[] attrIDs = { "distinguishedName",
                        "sn",
                        "givenname",
                        "mail",
                        "telephonenumber"};
                constraints.setReturningAttributes(attrIDs);
                //First input parameter is search base, it can be "CN=Users,DC=YourDomain,DC=com"
                //Second Attribute can be uid=username
                NamingEnumeration<SearchResult> answer = ctx.search("CN=Harish Patharla,OU=IG**,OU=IG**,OU=IG Users,DC=***,DC=**,DC=***", "igi\\patharh" + username, constraints);
                System.out.println("username =" + username);

After successful connection here is what the stack trace looks like:

Connection Successful.
javax.naming.directory.InvalidSearchFilterException: Missing 'equals'; remaining name 'CN=Harish Patharla,OU=IG**,OU=IG**,OU=IGUsers,DC=***,DC=**,DC=***'
	at com.sun.jndi.ldap.Filter.encodeSimpleFilter(Filter.java:310)

	at com.sun.jndi.ldap.LdapClient.search(LdapClient.java:520)
	at com.sun.jndi.ldap.LdapCtx.doSearch(LdapCtx.java:1962)

Could any one please help me with what i am doing wrong here?

The parameters i was passing into ctx.search() were wrong.I am getting response now with the asked details.

String[] attrIDs = { "distinguishedName",
"sn",
"givenname",
"mail",
"telephonenumber"};

But now i get an exception as below:

java.lang.NullPointerException
at com.sun.jndi.ldap.LdapNamingEnumeration.getNextBat ch(LdapNamingEnumeration.java:111)
at com.sun.jndi.ldap.LdapNamingEnumeration.nextAux(Ld apNamingEnumeration.java:245)
at com.sun.jndi.ldap.LdapNamingEnumeration.nextImpl(L dapNamingEnumeration.java:236)
at com.sun.jndi.ldap.LdapNamingEnumeration.next(LdapN amingEnumeration.java:184)

The line where its throwing the above exception is :
Attributes attrs = ((SearchResult) answer.next()).getAttributes();

I added a null check but it doesnot seem to work

if(!((SearchResult) answer.next()).getAttributes().equals(null)){

Attributes attrs = ((SearchResult) answer.next()).getAttributes();
}

Can anyone help me out with what is wrong?
