Script runner : Access LDAP attributes

[Julien REBILLARD]

Hello,

In a script runner, I am trying to access LDAP attributes.
I have this piece of code that works if I use the phone attribute :

import com.onresolve.scriptrunner.ldap.LdapUtil
import org.springframework.ldap.core.AttributesMapper
import javax.naming.directory.SearchControls
import javax.naming.directory.Attributes

def cnList = LdapUtil.withTemplate('LDAP') { template ->
template.search("", "(cn=123456)", SearchControls.SUBTREE_SCOPE, { Attributes attributes ->
attributes.get('telephoneNumber').get()
} as AttributesMapper<String>)

}

But if I try to retrieve the department attribute, I have this error message:

java.lang.NullPointerException: Cannot invoke method get() on null object

Could you help me so that I can retrieve the department attribute in a script

I know this is a very old post and this answer is super late, but I just spent a lot of time today troubleshooting the same issue. When your query returns multiple people, if that attribute is empty for even a single person the script will return a null pointer error.

You could surround your script in a try catch block, and if a NullPointerException is thrown take some other approach like pulling all the usernames (attribute samaccountname) and then iterate through them one at a time.
