Possible dereference of NULL

[VoroninArtemii]

There is a possible derefernce of NULL here:

nss-pam-ldapd/nslcd/passwd.c

Line 328 in b7841fc

cacheentry = dict_get(dn2uid_cache, dn);

The pointer dn2uid is checked here and we don't do anything after this block if the memory has not been allocated:

nss-pam-ldapd/nslcd/passwd.c

Lines 295 to 297 in b7841fc

	if (dn2uid_cache == NULL)
	dn2uid_cache = dict_new();
	if ((dn2uid_cache != NULL) && ((cacheentry = dict_get(dn2uid_cache, dn)) != NULL))

Thanks for pointing this out. It has been fixed in 91bb8c9. It should only be possible to trigger this if a call to malloc() failed.
