Hi,
we are facing issues with connecting LDAP, we are able to get the search result using the command ldapsearch in the terminal.
Following is the error message while executing the ldapimport.groovy file and also a folder is getting created
-----------------------------
Script execution failed.
error message: javax.script.ScriptException: java.lang.RuntimeException: Error processing search result: cn=John Doe,ou=people,o=customer1,dc=munidev,dc=org (java.lang.RuntimeException)

Again, this is for RHDS, not default LDAP.
There are some differences in the schema, which will have to be accounted for in the script, which is tailored for the Active Directory schema, so it will fail to find some attributes.
Example: node.setUsername(getStringAttribute(sr, "sAMAccountName"));
samaccountname is the login attribute in active directory, ours is "uid"

Hi Sreejith & wonky,
your script has some attributes that can not be found in your LDAP server:
1. You don't have a "uidNumber": change it to "uid"
2. You don't have a "name": change it to "sn"
3. Your mapping of users is incorrect, set it to:
if(objectClass.contains("OU")) {
umNode = createOUNode(sr, parent);
} else if(objectClass.contains("organizationalPerson")) {
umNode = createUserNode(sr, parent);
} else if(objectClass.contains("GROUP")){
umNode = createGroupNode(sr, parent);
} else continue;Here, I changed the person attribute to "organizationalPerson". You must change your OU and GROUP attributes accordingly.

Hi Eduardo,
Thanks a lot for your help. We are able to get sync the users now.

Hi Eduardo,
Now we are having another doubt that, actually we are hard-coding the Organisation name in this script ie
lul.setLdapBase("ou=people,o=customer1,dc=munidev,dc=org"); Instead of that can we get the 'o' from the URL.
For example if we are executing the url 'abc.reportserver.com' ,then we need to get the 'abc' as the 'o' in the ldapimport script. Or else is there any way to get the complete url in the script or just the first part.

Hi Sreejith,
You can access the HttpServletRequest URL if available by:
import javax.servlet.http.HttpServletRequest
HttpServletRequest req = GLOBALS.getInstance(HttpServletRequest.class)
return "URL: " + req.getRequestURL();You can also access to the parameters using req.getParameter("abc");
More information on HttpServletRequest here: https://tomcat.apache.org/tomcat-7.0-do … quest.html
Cheers,

Further, if executing a script via URL you have access to the predefined variable httpRequest as well as httpResponse which provide access to the HTTP request and response object.
