Hi,
If you are still encountering this issue, I'd recommend looking for errors that may be occurring in either the User Interface or backend (logs) by using our Troubleshooting Guide:
https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)
If you can share more details about the error you are receiving from the troubleshooting page, or the debugging LDAP steps, it's possible that someone here can help.
DSpace doesn't have a one-on-one support option available. But, if you require that level of support, you would want to contact one of our Registered Service Providers:
https://dspace.org/registered-service-providers/ These are for-profit companies that are experts in DSpace. They can provide one-on-one support or custom setups/hosting. But you'd need to reach out to them individually for more details or quotes.
