+          <p>[agent] Reading the value of the vacmViewTreeFamilyMask returns 
+	  it in the wrong (internal bitlist) format. </p>
+	  <p>The vacmViewTreeFamilyMask is defined as a bit string in the MIB
+	  (OCTET STRING). Internally a bitlist (list of 1's and 0's, 
+	  see <seealso marker="snmp_agent_config_files#vacm">vacm config file</seealso>
+	  for more info) is used. 
+	  However, the MIB implementation assumed the latter, effectively
+	  rendering all attempts to read/set masks via SNMP unsuccessful. </p>
+	  <p>Since the mask is used in hot paths (e.g. access permission checks 
+	  for each SNMP operation, the bitlist representation of the mask has 
+	  benefits (e.g. faster processing). Reading/writing the view mask 
+	  objects is less time-critical. Therefore, to fix the issue, convert 
+	  between the bitlist (internal) representation and bitstring 
+	  (external) when the vacmViewTreeFamilyMask objects are accessed. </p>
+	  <p>Also, the check of the vacm config file was invalid with 
+	  regard to the mask value. It was assumed to be a proper oid, which 
+	  is not strictly the case (see bitlist above). </p>
