and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

// Copying Grafana's original comment on the different cases for LDAP:
// There are several cases -
// 1. "admin" user
// Bind the "admin" user (defined in Grafana config file) which has the search privileges
// in LDAP server, then we search the targeted user through that bind, then the second
// perform the bind via passed login/password.
// 2. Single bind
// // If all the users meant to be used with Grafana have the ability to search in LDAP server
// then we bind with LDAP server with targeted login/password
// and then search for the said user in order to retrive all the information about them
// 3. Unauthenticated bind
// For some LDAP configurations it is allowed to search the
// user without login/password binding with LDAP server, in such case
// we will perform "unauthenticated bind", then search for the
// targeted user and then perform the bind with passed login/password.
// Note: the only validation we do on users is to check RequiredGroups.
// If RequiredGroups is not set and we can do a single bind, we don't
// even need to search. So our case 2 is not restricted
// to setups where all the users have search privileges: we only need to
// be able to do DN resolution via pure string substitution.
