Simplify uid replacement Regex declaration

    const ldap_reader_pass = process.env.LDAP_BIND_PW

    const ldap_base = process.env.LDAP_BASE

    var uid = query.email

    const searchTerm = "%u"

    const replacer = new RegExp(searchTerm, "g")

    const replacer = new RegExp("%u", "g")

    const filterstr = process.env.LDAP_GROUP_FILTER.replace(replacer, ldapEscape.filter`${uid}`) //replace all appearances

    console.log("filterstr:" + filterstr)

    var userDn = "" //ldapEscape.filter`uid=${uid}` + ',' + ldap_bd;
