LW_ERROR_INVALID_MESSAGE (The Inter Process message is invalid)


After a host level outage or host outage work, there's a rare case where older versions of AD Bridge cause the cache file /var/lib/pbis/db/lsass-adcache.filedb.* to become 0 bytes. The file also cannot be written to, so it causes an error when attempting to perform a domain join similar to the following:

root@host /opt/pbis/bin > pbis-status
LSA Server Status:
Compiled daemon version:
Packaged product version:
Uptime: 0 days 0 hours 0 minutes 47 seconds
[Authentication provider: lsa-activedirectory-provider]

root@pl000680 /opt/pbis/bin > domainjoin-cli join DOMAIN.LOCAL join-user
Joining to AD Domain: domain.local

join-user@DOMAIN.LOCAL's password:
Error: LW_ERROR_INVALID_MESSAGE [code 0x00009c46]
