SERIALIZED : 1. The directory lock (SYSDRLOK) is acquired
in exclusive mode for DIRECTXA processing.
2. The directory lock (SYSDRLOK) is acquired
in shared mode by HCPUDRAP to copy the
DAPPUSER and DAPPPASS fields.
NOTES : 1. DAPPLPWD is the actual length of the variable length
password (1-8 bytes) in DAPPPASS.
2. DAPPPASS is an encrypted version of the password
with the same length.
