Hi once again,
I've just had a closer look to the problem using gdb:
Program received signal SIGSEGV, Segmentation fault.
0x08055703 in auth_request_set_userdb_field (request=0x80a6008, name=0x0,
value=0x80a60d0 "[EMAIL PROTECTED]") at auth-request.c:1154
1154 if (strcmp(name, "uid") == 0) {
The problem occurs in auth_request_set_userdb_field which is called from
userdb-vpopmail.c on line 125 with parameter name = NULL.
Attached is a small patch that handles the NULL case for the name parameter
inside the auth_request_set_userdb_field function.
It works for me (no problems so far), but I think someone else should have
a look at it :=)
=> Patch is against dovecot 1.1 beta11.
Regards,
Moritz
