This may help, it was in another thread
Unfortunately, there can be only one label for an ADProvider at the moment. Therefore, if you have sub domains or domains in a different forest you will have to add those domains to the same security label by modifying the AuthInit and RoleInit fields in the securitylabels table in the Host Server database as follows :
• The AuthInit should be modified to contain both Domain NetBIOS names. E.g.
<AuthInit>
<Domain> PARENTDOMAIN </Domain><Domain> CHILDDOMAIN1</Domain>
</AuthInit>
• The RoleInit is a little trickier. You need to do the following :
Ø First you will have to set the “MultiDomain” property to “True” – Very Important
Ø Secondly you will have to edit the DataSources property(which you’ll see have to be escaped) by following my example below :
o DataSources=
<DataSources>
<DataSource Path="LDAP://DC= ParentDomain,DC=COM" NetBiosName=" PARENTDOMAIN "/>
<DataSource Path="LDAP:// DC= ParentDomain ,DC= ChildDomain1,DC=com" NetBiosName=" CHILDDOMAIN1"/>
</DataSources>
Here is an example script :
Use hostserver
Update securitylabels
Set authinit = '<AuthInit><Domain> PARENTDOMAIN </Domain><Domain> CHILDDOMAIN1</Domain></AuthInit>',
Roleinit =
'<roleprovider>
<init>ADCache=10;MultiDomain=True;IgnoreForeignPrincipals=False;IgnoreUserGroups=False;LDAPPath=LDAP://DC=DOMAIN1,DC=COM;ResolveNestedGroups=False;DataSources=
<DataSources>
<DataSource Path="LDAP://DC= ParentDomain,DC=COM" NetBiosName=" PARENTDOMAIN "/>
<DataSource Path="LDAP:// DC= ParentDomain ,DC= ChildDomain1,DC=COM" NetBiosName=" CHILDDOMAIN1"/>
</DataSources>
</init>
<login /><implementation assembly="ADUM, Version=4.0.0.0, Culture=neutral, PublicKeyToken=16a2c5aaaa1b130d" type="ADUM.K2UserManager2" /><properties><user><property name="Name" type="System.String" /><property name="Description" type="System.String" /><property name="Email" type="System.String" /><property name="Manager" type="System.String" /><property name="SipAccount" type="System.String" /><property name="ObjectSID" type="System.String" /></user><group><property name="Name" type="System.String" /><property name="Description" type="System.String" /></group></properties></roleprovider>'
