Problem with SSPI/Kerberos authorization on windows service

Dear programmers!

Today I have faced a serious problem, that I don't know how to approach.

I'm trying to implement an authorization service, using SSPI/Kerberos. I'm testing it on my local computer. When I implement server size as a windows service application, authorization process is cycling, i.e. function InitializeSecurityContext is always returning SEC_I_CONTINUE_NEEDED. If I compile server as a usual windows application, cycling never happens and authorization process successfully completes. Both client and server use the same code. The difference in authorization process begins to appear whet server calls function AcquireCredentialsHandle. Service is executing under the current user account.

I'l try to illustrate this with concrete data:

Case I. Both client and server are windows applications.

1. Client: AcquireCredentialsHandle; Returns: SEC_E_OK

2. Client: InitializeSecurityContext; Returns: SEC_I_CONTINUE_NEEDED; Token: (96, 61, 6, 10, 42, 134, 72, 134, 247, 18, 1, 2, 2, 3, 4, 0, 48, 45, 160, 3, 2, 1, 5, 161, 3, 2, 1, 16, 162, 20, 48, 18, 160, 3, 2, 1, 1, 161, 11, 48, 9, 27, 7, 69, 73, 115, 97, 121, 101, 118, 163, 11, 27, 9, 86, 73, 84, 80, 67, 46, 67, 79, 77)

3. Server: AcceptSecurityContext Returns: SEC_I_CONTINUE_NEEDED Token: (96, 130, 4, 45, 6, 10, 42, 134, 72, 134, 247, 18, 1, 2, 2, 3, 4, 1, 48, 130, 4, 27, 160, 3, 2, 1, 5, 161, 3, 2, 1, 17, 162, 130, 4, 13, 97, 130, 4, 9, 48, 130, 4, 5, 160, 3, 2, 1, 5, 161, 11, 27, 9, 86, 73, 84, 80, 67, 46, 67, 79, 77, 162, 30, 48, 28, 160, 3, 2, 1, 2, 161, 21, 48, 19, 27, 6, 107, 114, 98, 116, 103, 116, 27, 9, 86, 73, 84, 80, 67, 46, 67, 79, 77, 163, 130, 3, 207, 48, 130, 3, 203, 160, 3, 2, 1, 23, 161, 3, 2, 1, 2, 162, 130, 3, 189, 4, 130, 3, 185, 19, 169, 28, 176, 116, 14, 232, 162, 156, 233, 149, 48, 92, 255, 50, 12, 193, 3, 186, 15, 34, 188, 122, 124, 163, 106, 183, 17, 10, 169, 106, 102, 227, 11, 76, 92, 253, 71, 236, 84, 62, 86, 183, 49, 198, 5, 69, 8, 100, 10, 255, 106, 140, 168, 168, 119, 105, 244, 201, 170, 49, 21, 231, 3, 222, 144, 155, 234, 130, 119, 101, 163, 111, 116, 134, 251, 239, 130, 62, 98, 2, 0, 165, 221, 139, 93, 229, 128, 4, 134, 150, 215, 18, 64, 95, 25, 123, 245, 44, 111, 14, 97, 253, 227, 20, 113, 88, 255, 157, 92, 246, 170, 30, 8, 239, 80, 172, 153, 88, 236, 163, 112, 96, 115, 210, 238, 198, 126, 89, 161, 32, 59, 172, 233, 153, 48, 246, 185, 240, 97, 47, 114, 182, 117, 185, 58, 90, 122, 218, 165, 13, 105, 134, 76, 151, 243, 107, 170, 3, 35, 128, 207, 54, 95, 245, 112, 153, 208, 177, 122, 198, 32, 249, 17, 69, 17, 247, 187, 152, 44, 252, 19, 136, 49, 105, 116, 154, 24, 175, 167, 42, 5, 251, 193, 14, 133, 7, 68, 174, 85, 98, 221, 137, 246, 180, 234, 45, 21, 100, 197, 115, 209, 163, 28, 140, 76, 45, 227, 42, 190, 118, 169, 114, 135, 223, 151, 11, 204, 37, 178, 11, 174, 97, 168, 106, 39, 191, 29, 102, 64, 126, 57, 162, 123, 32, 69, 147, 168, 198, 24, 202, 196, 223, 90, 35, 163, 201, 11, 47, 23, 119, 217, 200, 75, 200, 27, 71, 147, 130, 218, 80, 58, 195, 206, 246, 188, 67, 242, 130, 46, 128, 57, 110, 51, 181, 43, 248, 36, 10, 96, 241, 181, 203, 98, 58, 158, 133, 197, 197, 196, 29, 28, 131, 183, 20, 42, 101, 86, 240, 179, 227, 94, 80, 97, 128, 60, 195, 42, 90, 141, 132, 102, 224, 114, 31, 190, 20, 40, 216, 38, 143, 214, 104, 48, 187, 251, 119, 52, 40, 26, 230, 50, 193, 134, 0, 38, 228, 166, 23, 192, 105, 224, 116, 11, 139, 155, 214, 6, 29, 152, 34, 73, 78, 67, 191, 109, 153, 108, 216, 176, 113, 158, 49, 245, 237, 9, 88, 255, 187, 18, 158, 18, 236, 83, 111, 111, 34, 181, 29, 46, 248, 184, 106, 29, 183, 134, 181, 38, 97, 13, 208, 242, 234, 186, 105, 112, 209, 229, 127, 200, 14, 138, 207, 150, 249, 95, 225, 85, 1, 230, 219, 168, 245, 90, 243, 194, 129, 49, 198, 165, 106, 45, 153, 149, 73, 0, 63, 60, 29, 169, 97, 243, 190, 47, 63, 137, 205, 108, 222, 89, 95, 252, 87, 108, 78, 195, 120, 242, 159, 64, 108, 84, 172, 6, 50, 123, 57, 148, 82, 87, 122, 190, 127, 124, 11, 41, 199, 14, 62, 102, 238, 173, 100, 218, 104, 209, 169, 44, 223, 59, 238, 77, 2, 58, 232, 229, 238, 157, 199, 217, 156, 1, 221, 11, 47, 175, 41, 16, 136, 227, 101, 227, 185, 82, 213, 195, 68, 194, 134, 33, 197, 251, 45, 14, 81, 9, 71, 174, 108, 71, 123, 41, 89, 111, 27, 107, 91, 117, 147, 49, 202, 242, 208, 191, 231, 21, 208, 30, 242, 120, 149, 252, 63, 11, 175, 52, 221, 99, 44, 97, 185, 117, 83, 213, 42, 75, 235, 85, 155, 101, 157, 29, 168, 94, 134, 26, 212, 212, 83, 77, 132, 232, 86, 124, 138, 211, 155, 136, 246, 44, 41, 111, 136, 208, 25, 176, 98, 27, 175, 116, 142, 207, 27, 8, 52, 63, 8, 203, 12, 140, 95, 93, 8, 143, 105, 191, 155, 49, 131, 59, 63, 140, 99, 186, 102, 59, 255, 242, 223, 207, 148, 252, 81, 77, 149, 166, 200, 26, 42, 66, 192, 201, 37, 36, 38, 110, 7, 210, 224, 220, 223, 233, 2, 231, 113, 91, 98, 73, 66, 242, 182, 85, 92, 240, 214, 173, 7, 78, 135, 10, 111, 145, 51, 124, 191, 49, 49, 84, 9, 241, 178, 47, 99, 147, 234, 210, 106, 156, 185, 203, 215, 111, 175, 202, 179, 59, 98, 115, 163, 60, 166, 29, 100, 100, 24, 102, 173, 210, 159, 253, 140, 136, 39, 142, 11, 229, 217, 142, 20, 23, 65, 150, 249, 253, 189, 150, 82, 109, 59, 217, 131, 27, 27, 63, 92, 43, 12, 93, 109, 146, 140, 60, 157, 81, 69, 152, 243, 151, 35, 203, 83, 200, 23, 175, 81, 15, 168, 81, 112, 32, 154, 227, 186, 82, 253, 110, 24, 17, 171, 201, 184, 207, 106, 92, 27, 165, 215, 156, 97, 90, 103, 77, 180, 230, 17, 213, 151, 216, 201, 58, 211, 217, 38, 95, 249, 33, 169, 161, 33, 236, 55, 18, 155, 166, 105, 94, 189, 233, 205, 0, 164, 147, 40, 178, 152, 201, 104, 56, 17, 118, 71, 161, 127, 99, 91, 107, 175, 169, 220, 38, 12, 88, 90, 213, 111, 249, 41, 7, 97, 175, 252, 44, 8, 191, 168, 140, 227, 6, 102, 44, 125, 23, 141, 226, 120, 174, 242, 40, 237, 174, 241, 83, 4, 250, 116, 112, 94, 2, 204, 54, 12, 163, 175, 68, 78, 155, 162, 241, 180, 123, 98, 137, 28, 17, 13, 22, 191, 224, 183, 227, 235, 17, 44, 184, 124, 189, 228, 7, 162, 16, 28, 116, 153, 72, 42, 55, 130, 164, 216, 70, 234, 86, 149, 240, 220, 47, 20, 190, 16, 151, 224, 80, 78, 228, 42, 137, 235, 230, 35, 72, 5, 167, 71, 165, 15, 201, 26, 141, 7, 125, 61, 110, 166, 248, 241, 187, 87, 248, 129, 79, 177, 123, 138)
