So, you could extract the allowed groups from sshd.conf, and query LDAP to get the users in those groups.

On our systems this would be something like:
Code:
for group in $(awk '/AllowGroups/ {$1="";print;exit}' /etc/ssh/sshd_config)
do
   ldapsearch -xZ -bou=groups,dc=domain,dc=com cn=${group} memberUID
done

but YMMV...

cldap_open(3LDAP)					      LDAP Library Functions						 cldap_open(3LDAP)

NAME
cldap_open - LDAP connectionless communication preparation SYNOPSIS
cc[ flag... ] file... -lldap[ library... ] #include <lber.h> #include <ldap.h> LDAP *cldap_open(char *host, int port); PARAMETERS
host The name of the host on which the LDAP server is running. port The port number to connect. DESCRIPTION
The cldap_open() function is called to prepare for connectionless LDAP communication (over udp(7P)). It allocates an LDAP structure which is passed to future search requests. If the default IANA-assigned port of 389 is desired, LDAP_PORT should be specified for port. host can contain a space-separated list of hosts or addresses to try. cldap_open() returns a pointer to an LDAP structure, which should be passed to subsequent calls to cldap_search_s(3LDAP), cldap_setretryinfo(3LDAP), and cldap_close(3LDAP). Certain fields in the LDAP structure can be set to indicate size limit, time limit, and how aliases are handled during operations. See ldap_open(3LDAP) and <ldap.h> for more details. ERRORS
If an error occurs, cldap_open() will return NULL and errno will be set appropriately. ATTRIBUTES
See attributes(5) for a description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | |Availability |SUNWcsl (32-bit) | | |SUNWcslx (64-bit) | |Interface Stability |Evolving | +-----------------------------+-----------------------------+ SEE ALSO
