#599 LDAP stop working after a certain time

[Alex]

Hi

I've got an error in DavMail. ldap requests from Thunderbird worked well. After a certain time, DAVMail pops up an error message. No way to make it work again, even by stopping DavMail and starting a new instance of it. In the logs, I found:

My system is: DavMail (latest) running on Linux Mint (Kubuntu 14.04) x86 with the latest java from Oracle installed.

Please help.

Thanx is advance

I found out, that ldap stop working if you enter an adress manually that is not in the directory. Further ldap lookups are no more possible.

I.E.: if you enter the ardess abc@def.ghi, the error message pops up (DavMail) and new searches even with a valid adress from the directory are not possible.

Was probably an Exchange bug
