Utilities
Default User Name and Password Verification
The Model 5390 server supports both native and proprietary support routines and integrated passwd
and passwd/shadow files (for more details, see Creating User Password Files starting on page
A15-11 and Modifying the Supplied Security Application starting on page A15-74).
When the proprietary routines are used for reading and writing files, these files are called
acp_passwd and, if enabled, acp_shadow; they are located in the installation directory. When the
native routines are used (selected with –DNATIVEPASSWD and/or –DNATIVESHADOW), erpcd
queries the standard library routines for validating user passwords. (The use of shadow files is
selected with –DUSESHADOW for both native and proprietary routines.)
Using the native routines allows erpcd to query NIS for user logins, enabling nicely distributed
databases; using the proprietary routines separates this query from the host code, enabling tighter
security control.
–u Invokes the acp_userinfo file syntax checker on the file
designated by filename. If filename is omitted, stdin is used.
Running this option does not interfere with any other erpcd
running on the system.
Parsing errors are printed on stderr. Error messages are in the
form:
<filename>: line <number>: <severity>: <description>
where <filename> is the name of the file, <number> designates
the line on which the error occurs, <severity> is either an error
or a warning (error indicates there is a serious parsing error;
warning indicates the parser remedied the situation by
conversion), and <description> describes the error.
