Note

This was taken from the hacks that miguel a.l. paraz map@i.nosp@m.phil.nosp@m..net did on radiusd-cistron-1.5.3 and migrated to a separate file. That, in fact, was again based on the original stuff from Jeph Blaize jblai.nosp@m.ze@k.nosp@m.iva.n.nosp@m.et done in May 1997.

Function Documentation

static rlm_rcode_t CC_HINT ( nonnull  )

static

Definition at line 196 of file rlm_pam.c.

Here is the call graph for this function:

static int do_pam ( REQUEST *  request, char const *  username, char const *  passwd, char const *  pamauth  )

static

Check the users password against the standard UNIX password table + PAM.

Note

For most flexibility, passing a pamauth type to this function allows you to have multiple authentication types (i.e. multiple files associated with radius in /etc/pam.d).

Parameters

request	The current request.
username	User to authenticate.
passwd	Password to authenticate with,
pamauth	Type of PAM authentication.

Returns

• 0 on success.
• -1 on failure.

Here is the caller graph for this function:

static int mod_instantiate ( UNUSED CONF_SECTION *  conf, void *  instance  )

static

Definition at line 66 of file rlm_pam.c.

static int pam_conv ( int  num_msg, struct pam_message const **  msg, struct pam_response **  resp, void *  appdata_ptr  )

static

Dialogue between RADIUS and PAM modules.

Uses PAM's appdata_ptr so it's thread safe, and doesn't have any nasty static variables hanging around.
