+
+        The public key was mathematically not correctly generated.
+        (It would have been nicer if we would have used BAD_PUBKEY for

+    This indicates that a server asked to try again later; thus it is
+    different from EAGAIN which is used by the local system.  This
+    code is for example used instead of h_error's TRY_AGAIN.

+
+GPG_ERR_SERVICE                 Service error
+
+    An error occured in a service component.  This is a generic

+
+GPG_ERR_LDAP_GENERAL            LDAP General error
+
+   Catch all error for LDAP.  Use when an error code could not be
+   mapped to a gpg-error code.
+
+GPG_ERR_LDAP_ATTR_GENERAL       LDAP General attribute error
+GPG_ERR_LDAP_NAME_GENERAL       LDAP General name error
+GPG_ERR_LDAP_SECURITY_GENERAL   LDAP General security error

+GPG_ERR_LDAP_X_GENERAL          LDAP Private error code
+GPG_ERR_LDAP_OTHER_GENERAL      LDAP Other general error
+
+  The 8 GPG_ERR_LDAP_*_GENERAL error codes may be used to map ranges
+  of LDAP errors to one specific code. OpenLDAP uses LDAP_xxx_RANGE(n)
+  macros for that mapping.  "Other general error" may be used similar
+  to "General error" for mapping of ranges.  Here are macros from
+  OpenLDAP for reference:
+
+  #define LDAP_ATTR_ERROR(n)     LDAP_RANGE((n),0x10,0x15) /* 16-21 */
+  #define LDAP_NAME_ERROR(n)     LDAP_RANGE((n),0x20,0x24) /* 32-34,36 */
+  #define LDAP_SECURITY_ERROR(n) LDAP_RANGE((n),0x2F,0x32) /* 47-50 */
+  #define LDAP_SERVICE_ERROR(n)  LDAP_RANGE((n),0x33,0x36) /* 51-54 */
+  #define LDAP_UPDATE_ERROR(n)   LDAP_RANGE((n),0x40,0x47) /* 64-69,71 */
+  #define LDAP_E_ERROR(n)        LDAP_RANGE((n),0x1000,0x3FFF)
+  #define LDAP_X_ERROR(n)        LDAP_RANGE((n),0x4000,0xFFFF)
+
