This article was previously published under Q236122 SYMPTOMS
An APPC Transaction Program configured to run on SNA Server may receive a BIND from the Host indicating support for the Already Verified (AV) and Persistent Verification (PV) in the BIND Security Support Indicators.
During subsequent conversation processing, if the Transaction Program changes conversation security from AP_NONE to AP_SAME in subsequent ALLOCATES, the APPC session may fail with a Primary Return Code : 0003 (AP_ALLOCATION_ERROR), Secondary Return Code : 080F6051 (AP_SECURITY_NOT_VALID), and the following event may be logged in the Windows NT Application Log:
Event ID: 63
Source: SNA Server
Description: Incorrect password received from client for logged on user.
EXPLANATION
An invalid password was specified for a signed-on PV user (user ID: user).
This password will be forwarded to the host to verify. If the password has
changed, then the host will accept the new password, and the conversation will continue without persistent verification.
ACTION
If host rejects password, then check password, and try again.
CAUSE
SNA Server fails to correctly implement user credential manipulation when the APPC conversation security is changed between ALLOCATE verbs.
