Application Error Message

[benjaminmclean]

Hi, 

I have a Cisco M1060 Management Appliance, and recently started having the following issues; Unable to log in with any user account apart from the Default "admin" account, if attempting to log in with any other account the following screen is shown (AppError.jpg attachment). If I try and log in via the CLI with any user account the putty session window just closes, but if I log in with the Default Admin account it logs in fine. 

Running a tail gui_logs I get the following output: 

Thu May 14 12:03:04 2015 Critical: An application fault occurred: ('egg/fast_rpc.py request|278', "<type 'exceptions.AttributeError'>", "'module' object has no attribute 'LDAPResult_to_string'", '[util/Aquarium.py screenLoop|408] [util/InternalLibrary.py inverseExtend|328] [util/InternalLibrary.py __call__|769] [screen/Controller.py __call__|27] [util/InternalLibrary.py __call__|769] [screen/CommonController.py __call__|66] [util/InternalLibrary.py __call__|769] [screen/AppController.py __call__|182] [util/InternalLibrary.py __call__|771] [screen/login.py __call__|68] [screen/Controller.py executeAction|70] [screen/login.py doLoginAction|204] [session/CoroSessionContainer.py login|250] [shared/ExternalAuth.py get_user_entry|303] [external_auth/__init__.py get_user_entry|183] [external_auth/__init__.py get_user_groups|382] [egg/verdict_cache.py get_verdict|127] [egg/verdict_cache.py do_scan|121] [external_auth/__init__.py _get_user_groups|330] [external_auth/ldap_rpc_client.py decorator|23] [external_auth/ldap_rpc_client.py get_user_groups|52] [egg/fast_rpc_proxy.py __method_caller__|20] [egg/fast_rpc.py request|278]')

This Error will also appear when doing certain actions within the web interface, most notably when trying to download or save the current config. 

Current AsyncOS Version is 8.1.1-033 

The Appliance has been rebooted.

Any Help would be much appreciated.

This is a known and previously seen defect for that version of AsyncOS for SMA:

https://tools.cisco.com/bugsearch/bug/CSCzv15527

Symptom:
When trying to log into the applinace, the user is presented with a note that an application fault has occurred and the user is not granted access to the appliance.

Conditions:
- The appliance is configured with LDAP Authentication.
- The username is configured in both the appliance and in LDAP.

Workaround:
- Verify that the credentials are correct and match the user's information as required by the appliance in the LDAP External Authentication Query.
- Remove LDAP External Authentication.
- The local "admin" account will always have access to the appliance.
- In AD try changing the port to Global Catalogue 3268
