LDAP issue. Cannot relogin with user that already was logined before and then logged out

Using the latest build (on 24 10 2012). Using LDAP authentification. First time logging user is normal and he is automatically arranged to default Usergroup. But when i logout and then try to login with the same user creditionals i receive an error (Unknown error code -1).
In openmeetings.log i see error message that it is unable to refresh session
this is the part of logfile about login problem

So i meant - first login of user is perfect. But later logins are causing errors. Solution is to delete problem user in administration section so after that it would be his first login again.
And this issue is only on LDAP login. LocalDB login is always perfect.
