Severity: 3-Major


When the localdb instance name contains "." character, Apmd wont be able to store the memcache entry. The store operation will fail. You will see a log "notice apmd[15593]: 01490000:5: mc_set_mkey() failed with error [11]."


The run time user information ( like login failure count ) is stored in memcache, if we are not able to store the entry in memcache, we will fail to authenticate the user.


This can occur when doing a localdb password change and the localdb instance name has a period in it.


Ensure your Localdb instance names do not contain a "." character.
