Call transaction <DS:TRAN.AL11>AL11</> on the application server, and
check whether the file "sapsecu.*" (NT,AS/400) exists in DIR_EXECUTABLE
or "libsapsecu.*" (UNIX). If the file is missing, install the newest

although the file exists, check the file access rights.
As an alternative tot he SAPSECULIB, you can use the SAPCRYPTOLIB (see
SAP Note 397175). To do this, you must set the following profile
parameters:
ssf/name = SAPSECULIB und ssf/ssfapi_lib = <path of the SAPCRYPTOLIB>.
In this case, check whether the file specified in profile parameter
ssf/ssfapi_lib exists and has sufficient access authorizations.
