[Users] Zimbra LDAP segfault?

[Stefan Sänger]

Hi All,

by now there is also an official "workaround":

  * stop all zimbra services (well - they will be stopped anyways... but
    just to be sure)
  *

    take a backup copy of "/opt/zimbra/conf/zmconfigd.cf"

  *

     From "/opt/zimbra/conf/zmconfigd.cf", remove following lines:
    LOCAL ldap_overlay_syncprov_sessionlog
    LDAP ldap_overlay_syncprov_sessionlog LOCAL
    ldap_overlay_syncprov_sessionlog

  * start zimbra services


According to zimbra support this is a new bug with patch23 and filed as 
ZBUG-2326.

Somehow I feel there should be a big red warning at 
https://wiki.zimbra.com/wiki/Zimbra_Releases/8.8.15/P23 ...

Best regards,

Stefan
