Hi,
I'm trying to get S4U2proxy to work with mod_auth_kerb. I compiled the patch here,http://sourceforge.net/p/modauthkerb/mailman/message/28531618/, into mod_auth_kerb but it crashes on a call to krb5_cc_default.
The offending line is line 283 of stdcc.c:
err = cc_initialize (&gCntrlBlock, ccapi_version_max, &gCCVersion, NULL);
The top of the stack trace is:
00000000()
> krb5_32.dll!stdccv3_setup(_krb5_context * context, _stdccCacheData * ccapi_data) Line 284 + 0x14 bytes C

Disassembly (the break is at the add instruction):
err = cc_initialize (&gCntrlBlock, ccapi_version_max, &gCCVersion, NULL);
6647164A push 0
6647164C push offset _gCCVersion (665A5DE4h)

66471658 call dword ptr [_pcc_initialize (665A7048h)]
6647165E add esp,10h
66471661 mov dword ptr [err],eax
_pcc_initialize watched values:
_pcc_initialize 0x665a7048 _pcc_initialize void *
*(long *)_pcc_initialize 0 long
Any help would be greatly appreciated!
Tim
