         realm
         attribute specifies the auth/reg or SASL authentication realm

         be selected by the SASL mechanism, or will be the same as the ID
         itself. Be aware that users are assigned to a realm, not a host,

         If this attribute is set to any value, clients must do STARTTLS

         Human-readable instructions to be returned to client when

         Password change only. When registration is disabled, it may
         still be useful to allow clients to change their password. If

         Note that the number of possible connections will be slightly

           and should use plain text authentication.

           'sha' specifies that the attribute in pwattr holds a base-64

           'ssha' specifies that the attribute in pwattr holds a base-64
           SHA-1 hashed password appended with 32 bits of salt and beginning
           with the string {SSHA}.
           'crypt' specifies that the attribute in pwattr holds a UNIX-style
           crypt(3) hashed password.
           'bind' specifies that the password is not stored in an attribute
           but is authenticated directly by the LDAP server by binding
           using the user's DN. This should be compatible with the
           widest variety of LDAP servers.
