This is to address and issue with missing permissions for a Blackberry Admin aka BESAdmin

BESAdmin is the account used to administer Blackberry Enterprise Server christened so by Blackberry.
If any user in the organisation needs to use their Blackberry device, the account
which is administrating the Blackberry Enterprise server needs to be granted SEND AS Permission for the user account.

There are 2 main reasons why SEND AS Permission vanish from the BESAdmin account

—————————————————————————————————————————————————————
1.  There is a permissions inheritance broken at an OU level in ADUC and we grand “SEND AS” permission to that OU for BESAdmin. It’s obvious that when AD replication happens, the change would be propagated from top level which causes SEND AS Permission to VANISH for BESAdmin.

2.  We set“SEND AS” permission for a Domain Admin which should be addressed separately and that’s by design.

To resolve this issue:

——————————————————–

You must create and configure a Microsoft Windows account and mailbox in the Microsoft Active Directory service for the BlackBerry Enterprise Server and the BlackBerry Manager so that they can authenticate to the Microsoft Exchange messaging server.

1.  Open Active Directory Users and Computers.
2.  Create an account with the following attributes:

• Name : BESAdmin
• User location : Create a Microsoft Exchange mailbox
• Group membership : Domain User

3. Assign this account the Send As permission for all user accounts in the User container of the Active Directory domain.
4 Send a test message to activate the new mailbox.

Enable BlackBerry device users to send messages in a Microsoft Exchange
————————————————————————————————————————–

1. On any computer within your domain, on the taskbar, click Start > Administrative Tools > Active Directory Users and Computers.
2. In the View menu, click Advanced Features.
3. Right-click the domain root.
4. Click Properties.
5. On the Security tab, click Advanced.
6. Click Add.
7. Type BESAdmin.
8. Click Check Name.
9. Click OK.
10. In the Apply Onto drop-down list, click User Objects.
11. In the Allow column, select the Send As check box.
12. Click Apply.
13. Click Ok.

Configure permissions for the Microsoft Windows account

—————————————————————————————————–

On each computer that you want to install the BlackBerry Enterprise Server components on, you must configure the permissions of the Microsoft Windows account that you plan to use to install the BlackBerry Enterprise Server components.

1. On the taskbar, click Start > Programs > Administrative Tools > Local Security Policy.
2. Configure the following permissions for the Microsoft Windows account:
• log on locally with local permissions (if not assigned by default)
• log on as a service
3. On the taskbar, click Start > Programs > Administrative Tools > Computer Management.
4. Add the Microsoft Windows account to the local administrators group.

When we grant access to BESAdmin on a domain level, points to note:
————————————————————————————————————————————–

1. BESAdmin by design, should be a Domain user and not a Domain Admin
2. “Allow inheritable permissions from parent to propagate to this object” should not be broken at any OU level in ADUC.
3. The whole procedure is to grant access to Domain users and not for Domain Admins.
4. Even if ExBPA shows broken permissions, need to check it manually for every OU in ADUC

Domain Admins should be addressed specifically (very Important)
————————————————————————————————————————————
If a user who is a member of the Domain Admin group, needs to be granted BB access,
the same should be addressed separately.

———————————————————————————————————————————————————————-
For the ADMINSDHolder, Permissions inheritence is uncheked and it’s by default.
———————————————————————————————————————————————————————-

The Active Directory directory service has a process that makes sure that members of protected groups do not have their security descriptors manipulated. If a security descriptor for a user account that is a member of a protected group does not match the security descriptor on the AdminSDHolder object, the user’s security descriptor is overwritten with a new security descriptor that is taken from the ADMINSDHolder Object
The Send As right is delegated by modifying the security descriptor of a user object. Therefore, if the user is a member of a protected group the change is overwritten.

Do not to use accounts that are members of protected groups for e-mail purposes. If you require the rights that are afforded to a protected group, have two Active Directory user accounts. These Active Directory accounts include one user account that is added to a protected group and one user account that is used for e-mail purposes and at all other times.

To handle the administrative users the appropriate permissions need to be set on the AdminSDHolder container. The easiest way to do this is with the dsacls command.

To use it you’ll need the Windows Server 2003 Support Tools installed. The syntax of the command is as follows:

—————————————————————————————————————————————————————————————————–

dsacls “cn=AdminSDHolder,cn=System,dc=domain,dc=com” /G “domain.com\BESAdmin:CA;Send As”
—————————————————————————————————————————————————————————————————–

To grant these permissions on the adminSDHolder object, follow these steps:
1. In Active Directory Users and Computers, click Advanced Features on the View menu.
2. Locate the adminSDHolder object. The object is in the following location for each domain in the Active Directory forest:
CN=adminSDHolder,CN=System,DC=domain,DC=com Here, DC=domain,DC=com is the distinguished name of the domain.
3. Right-click adminSDHolder, and then click Properties.
4. In the Properties dialog box, click the Security tab and then click Advanced.
5. In the Access Control Settings for adminSDHolder dialog box, click Add on the Permissions tab.
6. In the Select User, Computer, or Group dialog box, click the
account to which you want to grant related permissions (BESAdmin), and then click OK.
7. In the Permissions Entry for adminSDHolder dialog box, click This object only in the Apply onto box, and then click List Contents, Read All Properties, and Write All Properties rights.
8. Click OK to close the Permissions Entry for adminSDHolder dialog box, the Access Control Settings for adminSDHolder dialog box, and the adminSDHolder Properties dialog box.

NB: Wait for AD replication and monitor the server for at least 20 – 25 minutes before confirming issue resolution.
