This is NSS with a Cmake Buildsyste To compile a static NSS library for Windows we've used the Chromium-NSS fork and added a Cmake buildsystem to compile it statically for Windows. See README.chromium for chromium changes and README.trustbridge for our modifications.

126 * This function checks the collection of LDAPClient connections held by the
127 * AIAMgr pointed to by "aiaMgr" for one matching the domain name given by
128 * "domainName". The string may include a port number: e.g., "betty.nist.gov"

130 * stored at "pClient". Otherwise, an LDAPClient is created and added to the
131 * collection, and then stored at "pClient".
132 *
133 * PARAMETERS:
134 * "aiaMgr"
135 * The AIAMgr whose LDAPClient connected are to be managed. Must be
136 * non-NULL.
137 * "domainName"
138 * Address of a string pointing to a server name. Must be non-NULL.
139 * An empty string (which means no <host> is given in the LDAP URL) is
140 * not supported.
141 * "pClient"
142 * Address at which the returned LDAPClient is stored. Must be non-NULL.
143 * "plContext"
144 * Platform-specific context pointer.
145 * THREAD SAFETY:
146 * Thread Safe (see Thread Safety Definitions in Programmer's Guide)
147 * RETURNS:
148 * Returns NULL if the function succeeds.
149 * Returns an AIAMgr Error if the function fails in a non-fatal way
