Data Source configration File (LDAP)inactive

Hi Experts,

i am doing SPNego configuration .i have followed SAPnotes 994791.But for that I have to upload DataSourceConfiguration_ads_readonly_db_with_krb5.xml

in the UME LADP data in configtool.

And we have to test connection there in the configtool by selecting the .xml file from the configuration file.

But I am not able to select that file as all are in inactive mode.

i have tried both offline and online but in every option the datasource configuration file is in inactive mode.

What can be problem ?And how can i get all those columns active in the configtool.

Thanks
