Sharing the pointer to the supported controls would allow to use the actual set. Something along the line

struct BackendDB { char be_ctrlsbuf[SLAP_MAX_CIDS + 1]; char *be_ctrls; };

All backends would have be_ctrls = be_ctrlsbuf, but back-relay would set it to NULL, and temporarily set it to the relayed database's be_ctrlsbuf for the duration of an operation. Modules wouldn't be able to register new controls because the pointer is null otherwise.

Of course, this wouldn't work since it implies modifying the BackendDB structure, which is read-only :(
