[Dovecot] Dovecot ldap connection reconnecting after inactivity

[Aliet Santiesteban Sifontes]

Hi people, I have a setup configured using ldap, I have noticed that after a
period of user inactivity if a client open connections to dovecot first
attemps fails with this:

Nov 16 19:34:43 cl05-02 dovecot: auth: Error:
ldap(user at xxx.xx.xx,172.29.13.26):
Connection appears to be hanging, reconnecting

After the connections to ldap has been restablished everything starts
working ok, is this a expected behavior or I'm missing something??

Best regards
