If required, an authorization control can be activated which, depending on the selected sender mailbox, allows or disables the use of the SEPPmail Secure E-Mail Gateway encryption functions.

 

For this purpose, the entry of additional registry keys is required. This defines the connection to and query in LDAP, as shown in the following table

 

Name

Type

REG_

Data

(Example)

Description

LDAPPermissionCheckActive

DWORD

0/1

Controls whether the permission check is activated in general.

LDAPServerAddress

SZ

myldap.local

Address of the LDAP server

LDAPUsername

SZ

tech_ldap

User that is authorised to query the LDAP. If there is no entry, the currently logged-in user is used.

LDAPPassword

SZ

password

Password of the user. If there is no entry, the password of the currently logged-in user is used.

LDAPAuthenticationTypes

SZ

secure

fast

bind

Authentication method to use for the LDAP login.

Multiple values can be indicated, separated by commas.

Possible values can be found under

AuthenticationTypes Enumeration

.

If the entry does not exist or is empty, NTLM is used as the authentication method (secure).

LDAPOrganizationalUnit

SZ

OU=Users,

DC=test,

DC=server,

DC=tld

LDAP search path in which the user objects are located.

 

LDAPQuery

SZ

(&(mail={0})(SEPPmailPermission=*))
(!(SEPPmailPermission=\00)))

LDAP query.

In the example, using the sender email address "&(mail={0})" (where {0} is replaced by this address in the search query) in the search path (see "Name LDAPOrganizationalUnit"), the corresponding user object is queried in LDAP.

With "(SEPPmailPermission=*)", the attribute "SEPPmailPermission" is queried in the corresponding user object.

With "(!(SEPPmailPermission=\00))" it is specified that if the value is present, it must not be empty in order to receive a positive return value (if applicable, see also Searching for Empty Attribute Values).

 

empty

anchor link Note:

If a new attribute for the user objects is added to the AD schema (in "Data (Example)" "SEPPmailPermission", if applicable, please refer to example Creating a new attribute for user objects in the Active Directory schema), this is available in every user object.

Thus a search for the attribute alone "(SEPPmailPermission=*)" is not useful, which is why an additional check should be made as to whether a value is also assigned to the attribute "(!(SEPPmailPermission=\00))", i.e. the attribute is not empty.

It may also be necessary to ensure that the value of the attribute does not contain a space, as the value would then not be empty.
