After upgrade from 4.0.10 to 4.2.11 , returning users autenticated via LDAP (with ExternalAuth plugin), now have wrong polish characters in their names, oragnization etc.
I turned debug options and see something like this: [27516] [Tue May 26 10:58:01 2015] [debug]: UPDATED user mkolbe: User mkolbe: City changed from 'Ostróda' to 'Ostróda' (/usr/local/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth.pm:421) [27516] [Tue May 26 10:58:01 2015] [debug]: UPDATED user mkolbe: User mkolbe: Organization changed from 'Dział IT' to 'DziaÅ� IT' (/usr/local/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth.pm:421) Then RT allow user to login but corrected data by hand is overwritten by data from Windows AD with wrong characters. Any hints for solving this?
