Lightweight Directory Authentication Protocol (LDAP)
The Lightweight Directory Access Protocol (LDAP) is an application protocol supported by the
BMC for the purpose of authentication and authorization. The BMC user connects with an LDAP
server for login authentication. This is only supported for non-IPMI logins including the
embedded web UI and SM-CLP. IPMI users/passwords and sessions are not supported over
LDAP.
LDAP can be configured (IP address of LDAP server, port, and so on) from
the BMC’s
Embedded Web UI. LDAP authentication and authorization is supported over the any NIC
configured for system management. The BMC uses a standard Open LDAP implementation for
Linux.
Only open LDAP is supported by BMC. Windows and Novel LDAP are not supported.
4.6 BMC Firmware Update
4.6.1
The BMC firmware release Number
The BMC firmware releases are numbered as follows:
AB.CD.XXX
Where:
CD
is a two digit number starting with 00 for the first release. This is the number returned in
minor ID in Get Device ID response.
B
is major release number (1 for the first major release typically at first production shipment).
A
is point release indicator (A=0 means this is a regular official release, A=1 means this is a
point release for limited distribution). A hex representation of “AB” is returned in major ID in Get
Device ID response.
XXX
is the build number for internal tracking. This number is returned in OEM bytes of Get
Device ID response.
4.6.2
Boot Recovery Mode
The BMC’s boot block supports firmware transfer updates. The Operational Firmware Transfer
mode preserves several files in the PIA Linux file system. Boot Recovery mode cannot preserve
the files because it does not understand Linux file systems, and treats it as a large binary data
section. This means a Boot Recovery update completely replaces the PIA with the factory
default version: an empty SEL, a default SDR, and default IPMI configuration and user settings.
Boot Recovery mode can successfully complete an update in some situations where the
Operational Firmware Transfer mode will fail. If there is an incompatibility or bug in the
operational code causing it to crash or hang, only a Boot Recovery Mode Update works.
Another example is if the flash layout of the sections changes across an update. Because the
operational Firmware Transfer mode tries to preserve the contents of the PIA section, in this
