Kerberos authentication works only for a few hours

[dsicpam84]

Hello everyone,

I'm configuring an Alfresco CE with Kerberos SSO authentication.

I had many difficulties tomake it work, but it works fine now.

The only remaining problem is that the authentication works during the day but after a while (a few hours may be), it stops working.

So every morning, I have to restart Alfresco and then the Kerberos SSO authentication works again.

Is there some parameters somewhere in Alfresco to fix this ? Is it a good practice to resart Alfresco everynight to solve the problem or is there another way ?

I can't find any clue about this.

Thanks in advance for your help.
