Steps to reproduce:

1. Adding LDAP as authentication method using JIT provisioning something went wrong with the configuration.
   Now it's impossible to update the configuration via GUI without getting the error message "Details Cannot update authentication
   Invalid LDAP JIT provisioning user group mapping configuration." or the error message "Invalid LDAP Configuration".
   We can't delete the old configuration or add a new configuration without getting these error messages.

Result:
Uploading two screenshots and a textfile with the contents from table userdirectory_ldap.
Aware of that more tables are involved in ldap authentication but the main config resides here I think.
Expected:
See screenshot....
See attached patch file...
