Hi
Thank you for reply.
I had tested migration of LDAP user to Nextcloud Local user. But in that case LDAP was Live. Just removed LDAP user from oc_ldap_user_mapping and created user of same uid, display name in oc_users and left the password empty. Then At GUI interface clicked on Fogot Password all went well. For more details this is perfect procedure, but difference is that I did with phpmyadmin
But now my case is different i.e. LDAP is down. Now i am stuck to retrieve user accounts. There should be workaround.
Please Suggest
