Comment 6 for bug 572271

Some more testing but no success.

I stopped the lsasd service, made a backup of the registry.db file and then tried manually inserting 2592000 (30 days) into the CacheEntryExpiry value.

Restarted the service and ran lw-eventlog-cli -s - localhost to see there was any change. There wasn't.

Event Description....... Likewise authentication service provider configuration settings have been reloaded.

     Authentication provider: lsa-activedirectory-provider
     Current settings are...
     Cache reaper timeout (secs): 2592000
     Cache entry expiry (secs): 14400
     Space replacement character: '^'
     Domain separator character: '\'
     Enable event log: false
     Logon membership requirements:
        <No login restrictions specified>
     Log network connection events: true
     Create K5Login file: true
     Create home directory: true
     Sign and seal LDAP traffic: false
     Assume default domain: true
     Sync system time: true
     Refresh user credentials: true
     Machine password sync lifetime: 2592000
     Default Shell: /bin/bash
     Default home directory prefix: /home
     Home directory template: %H/%D/%U
     Umask: 18
     Skeleton directory: /etc/skel
     Cell support: Unprovisioned
     Trim user membership: true
     NSS group members from cache only: false
     NSS user members from cache only: false
     NSS enumeration enabled: false
     Domain Manager check domain online (secs): 300
     Domain Manager unknown domain cache timeout (secs): 3600

Then I ran sudo lw-edit-reg and see a value change "CacheEntryExpiry"=dword:32393532
