Master Password Fails to Reset Individual Password (CSSM_ERRCODE_MEMORY_ERROR)
This problem appears to be similar to the thread below where user Linc Davis provided the correct solution.
My friend has an older Macbook running OS X 10.5.8. His account (/Users/davidreaves) uses FileVault and he has forgotten his password. He does remember his master password, which is accepted from the main login/reset password window and pops up another window to allow an individual account password reset. However, the individual password reset fails with no information as to why.
I followed instructions from another source that allowed me to go through the initial Macbook setup sequence and create a new user account with administrative privileges. From there, I went to System Preferences -> Accounts and attempted to reset the password on his personal account using the master password. This attempt also failed, but with a pop-up error message that reads
Reset password failed.
CSSM_ERRCODE_MEMORY_ERROR
After searching this forum, I discovered the thread above and was following the instructions given by user Linc Davis up until the results diverged. Davis asks the OP to execute
sudo find / -xdev -name *.sparse*
When I do that, the result is
/Users/.davidreaves/davidreaves.sparsebundle
Since this sparsebundle file was found in a different location from the OP's in the other thread, I don't know what, if anything, to do to proceed. Can anyone guide me through the remainder of the process to recover this account using the master password? Many thanks!
MacBook, Mac OS X (10.5.8)
