[xwiki-users] Random logoff when using LDAP authenticator

Hi, I'm getting randomly logged off when using the LDAP authenticator in v1.3.1. I'm wondering if anyone else is experiencing this. At the end are the thread dumps I captured in two individual cases and a snippet of my LDAP configuration. Thanks, Benjamin xwiki.authentication.ldap.UID_attr=sAMAccountName xwiki.authentication.ldap.fields_mapping=name=sAMAccountName,last_name=sn,first_name=givenName,fullname=displayName,mail=mail,ldap_dn=dn xwiki.authentication.ldap.update_user=0 xwiki.authentication.ldap.group_mapping=XWiki.XWikiAdminGroup=CN=Wiki Admins (omitted the rest) xwiki.authentication.ldap.mode_group_sync=always -----------------Thread Dump #1----------------------- 09:43:53,819 [ http://bl.local:8080/xwiki/xwiki/bin/view/Main/DocumentDoesNotExist] [http-8080-22] ERROR base.Cache -
