Re: centos 7 dovecot 2.2.10 segmentation fault on devcot/auth using ldap driver in userdb
The crash seems involved with bad handled AD response
DSID-0C090627,.comment:.In.order.to.perform.this.operation.a.successful.bind.must.be.completed.on.the.connection.
when this occurs dovecot got a segmentation fault
this bug probably has been corrected (changelogs aren't clear) because this
response is well handled on dovecot-2.2.18-2.fc21.x86_64
