LDAP filter allow the subStrings Filter, like follow theses sources show:
ldapWiki, ldap.com.

Replay the bug:

	//Search value with ldap and filter
	searchRequest := ldap.NewSearchRequest(
		config.UserBaseDN,
		ldap.ScopeSingleLevel, ldap.NeverDerefAliases, 0, 0, false,
		fmt.Sprintf("(&(cn=%s*))", input),
		[]string{config.UserNameAttr, "dn", "displayname", "givenname", "sn", "mail"},
		nil)

	sr, err := login.conn.Search(searchRequest)
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}

Expected Result:

We obtain all users where their Cn begin with the substring input

Real Result:

An error from LDAP:
LDAP Result Code 53 "Unwilling To Perform": Unsupported filter: message.FilterSubstrings{type_:"cn", substrings:[]message.Substring{"e", "e"}} message.FilterSubstrings

Conclusion:

Bottin don't consider the SubString Filter like a basic filter.
Add this filter in further version will help greatly the research for users or groups.
