BADI CRM_DOC_AUTHORITY for Auth. Checks on docs not processed in 7.0?

Hello,

after upgrading from CRM 4.0 to 7.0 it seems that BAdI CRM_DOC_AUTHORITY for Authorization Checks on Documents is not processed in CRM 7.0. Note 720434 seems to be not valid for CRM releases with WebUI (>= 5.2) but BAdI entry is still visible in Customizing (SPRO) in ../Customer Relationship Managemnt / Basic Functions / Content Management / Business Add.Ins (BAdIs) .

Are there any other people who experienced this situation? Is this BAdI not supported in 7.0?

Thx

Robert
